Answer
\(5x(x + 8)\)
Solution
Factor the expression \( 5x^2+40x \).
Factor the expression by following steps:
- step0: Factor:
\(5x^{2}+40x\)
- step1: Rewrite the expression:
\(5x\times x+5x\times 8\)
- step2: Factor the expression:
\(5x\left(x+8\right)\)
The factored form of the expression \(5x^2+40x\) is \(5x(x+8)\).
Now, let's check by multiplying:
\(5x(x+8) = 5x^2 + 40x\)
Multiplying the terms, we get:
\(5x^2 + 40x = 5x^2 + 40x\)
Therefore, the factored form \(5x(x+8)\) is equivalent to the original expression \(5x^2+40x\).

The Deep Dive
You can factor out the greatest common factor from the expression \(5x^2 + 40x\). The greatest common factor here is \(5x\), so you can rewrite the expression as \(5x(x + 8)\). To check your work, simply multiply \(5x\) by \((x + 8)\): \(5x \cdot x + 5x \cdot 8 = 5x^2 + 40x\), which means your factorization is correct! Now you have \(5x(x + 8)\) as the factored form of your original expression. Remember, factoring is just like unwrapping a present — you’re revealing what’s inside!
