Answer:

[tex]10x^4+65x^3-25x^2[/tex]

Step-by-step explanation:

Multiply 5x^2(2x^2 + 13x − 5)

[tex]5x^2(2x^2 + 13x - 5)[/tex]

Multiply 5x^2 inside the parenthesis

[tex]5x^2 * 2x^2 = 10x^4[/tex]

[tex]5x^2 * 13x = 65x^3[/tex]

[tex]5x^2 * (-5) = -25x^2[/tex]

Collect all the terms together

[tex]10x^4+65x^3-25x^2[/tex]
