🧮 algebra

1. Let's clarify the problem: You want to understand why, in some calculations, we multiply by 11 and 10 instead of directly dividing $v_{11}$ by $v_{10}$ and then taking the 11th

1. **State the problem:** We have the addition of three 3-digit numbers where $x$ and $y$ are single digits, and the sum is a 4-digit number: $$

1. **Problem 1: Identify which is NOT a factor of the polynomial $P(x) = x^3 - \pi x^2 - x + \pi$.** We test each candidate factor by evaluating $P(x)$ at the root of the factor. I

1. The problem is to work with a number represented by $x$ instead of $W$. 2. This means wherever the variable $W$ was used, we now replace it with $x$.

1. **Problem Statement:** A field of paddy can be harvested by 10 people in 20 days. If 2 people are less (i.e., 8 people), how many days will it take to harvest the same field? 2.

1. **Problem 1:** For what number $k$ is $x+1$ a factor of $f(x) = 2x^6 - kx^3 + 5x - 1$? By the Factor Theorem, if $x+1$ is a factor, then $f(-1) = 0$.

1. The first problem asks for the sum of the first four terms of a geometric sequence where the first term $G_1 = \frac{1}{4}$ and the common ratio $r = 3$. 2. The formula for the

1. **Simplify the expression** $\frac{n}{5-n} + \frac{2n-5}{n-5}$. Note that $n-5 = -(5-n)$, so rewrite the second fraction:

1. **State the problem:** We need to find how many kids (k), parent (p), and sponsor (s) tickets were sold given the total tickets sold is 400 and total revenue is 6800. 2. **Defin

1. Problem 1: Two numbers have a sum of 432 and their GCF is 12. We need to find the greater number from the options 18, 36, 72, 16. 2. Since the GCF is 12, both numbers can be wri

1. The problem is to complete the square for the number 4. 2. Completing the square usually applies to quadratic expressions, but here we interpret it as expressing 4 as a perfect

1. **State the problem:** Find the greatest number divisible by both 3.5 and 4.5. 2. **Understand the problem:** To find a number divisible by both 3.5 and 4.5, we need to find the

1. The problem asks for the values of $k$ such that the quadratic equation $2x^2 + kx + 2 = 0$ has no real roots. 2. Recall that a quadratic equation $ax^2 + bx + c = 0$ has no rea

1. **State the problem:** We are given a quadratic function $f(x) = x^2 + bx + 1$ and asked to find its minimum value. 2. **Recall the formula for the vertex of a quadratic:** For

1. **State the problem:** Simplify the expression $\sqrt{72} + \sqrt{50} - \sqrt{25}$.\n\n2. **Recall the formula and rules:** The square root of a product can be expressed as the

1. **State the problem:** Evaluate the function $f(x) = x^2 + 2x - 3$ at $x = -2$. 2. **Write the formula:** The function is given by

1. The problem is to evaluate or understand the value of the variable $x$ given as $x = -2$. 2. Here, $x$ is simply assigned the value $-2$. There is no equation to solve or expres

1. The problem is to evaluate or understand the value of $x$ given as $x = -3$. 2. Here, $x$ is simply assigned the value $-3$. This means $x$ is a constant with a negative value.

1. **State the problem:** We are given the quadratic function $f(x) = x^2 + 2x - 3$ and want to analyze it. 2. **Formula and rules:** A quadratic function is generally written as $
