Question

(3x+4)(3x-4)
(5x+6x²)(8x²-2x)
(4x³+6x²)(8x+12)
3x⁶(7x+8x⁶)
9x⁸(7x¹⁰- 4x¹⁸)​

Answer 1

Explicación paso a paso:

$(3x + 4)(3x - 4) = 9x^{2} - 12x + 12x - 16 \\ \\ 9x^{2} - 16$

$(5x + 6x^{2} )(8 {x}^{2} - 2x) = 40 {x}^{3} - 10 {x}^{2} + 48 {x}^{4} - 12x^{3} \\ \\ 40 {x}^{3 } - 12 {x}^{3} + 48x^{4} - 10 {x}^{2} \\ \\ = 28x ^{3} + 48 {x}^{4} - 10 {x}^{2}$
