Question

Упростите выражения：

а)(3x-8)^2+(4x-8)(4x+8)+100x

b)(m^3+6n^2)^2-(6n^2-m^3)^2

c)(9z+2x^4)^2-(2x^4-9z)^2

Answer 1

надеюсь мой почерк понятен

Answer 2

$a)9x {}^{2} - 48x + 64 + 16x {}^{2} - 64 + 100x {}^{2}$

$25x {}^{2} + 52x$

$b)2m {}^{3} \times 12n {}^{2}$

$24m {}^{3} n {}^{2}$

$c)(9z + 2x {}^{4} + 9x)(9z \times 2x {}^{4} + 2x {}^{4} - 9x)$

$9(z + x)(9z + 4x {}^{2} - 9x)$
