question
factor the expression completely.
$40x^3 + 36x^5$

Explanation:

Step1: Identify GCF of terms

Find GCF of 40, 36, $x^3$, $x^5$: $\text{GCF}=4x^3$

Step2: Factor out the GCF

$40x^3 + 36x^5 = 4x^3(10 + 9x^2)$

Step3: Check for further factoring

$10+9x^2$ has no real factors, so stop.

Answer:

$4x^3(9x^2 + 10)$
