Multiply.
5x2(2x2 + 13x - 5)

10x4 + 65x3 - 25x2

10x2 + 65x - 25

7x2 + 18x - 10

7x4 + 18x3 - 10x2

Answer 1

the numbers aftr x are exponents

Answer 2

these are the answers 10x4 + 65x3 - 25x2

10x2 + 65x - 25

7x2 + 18x - 10

7x4 + 18x3 - 10x2

Answer 3

ok, for exponents, use the ^ key next time. IE 7 to the 2nd power is 7^2.

so...
\[5x^2(2x^2+13x-5)\]
would factor fairly simply. for all the numbers, times them together. for all the powers of x's, add them together.
\[10x^4+65x^3-25x^2\]

Answer 4

Thank you ^.^
