5x2(2x2 + 13x − 5) what’s the answer

10x^4+65x^3-25x^2 that is if you are asking to Simplify

Step-by-step explanation:

Apply the distributive property.

5x^2 (2x^2) + 5x^2 (13x) + 5x^2 * -5

Rewrite using the commutative property of multiplication.

5 * 2 (x^2x^2) + 5x^2 (13x) + 5x^2 * -5

Rewrite again like the step before.

5 * 2 (x^2x^2) + 5 * 13 (x^2x) - 25x^2

Multiply -5 by 5

5 * 2 (x^2x^2) + 5 * 13 (x^2x) - 25 x^2

Simplify each term.

Multiply x^2 by x^2 by adding the exponents.

5 * 2x^4 + 5 * 13 (x^2x) - 25x^2

Multiply 5 by 2.

10x^4 + 5 * 13 (x^2x) - 25x^2

Multiply x^2 by x by adding the exponents.

10x^4 + 5 * 13x^3 - 25x^2

Multiply 5 by 13.

10x^4 + 65x^3 - 25x^2

answer is c
