porfa ayuda

Answer 1

¡Hola!

Problema A.

$(x + 8)( x - 3) \\ \\ \\ x(x - 3) = {x}^{2} - 3x \\ \\ 8(x - 3) = 8x - 24 \\ \\ \\ {x}^{2} - 3x + 8x - 24 \\ \\ \\ \boxed{{x}^{2} + 5x - 24}$

Problema B.

$(5x-8)(5x+8) \\\\\\ 5x(5x+8)=25x^{2}+40x \\\\ -8(5x+8)=-40x-64 \\\\\\ 25x^{2}+40x-40x-64 \\\\\\ \boxed{25x^{2}-64}$

Espero que sirva y saludos.
