Question

ajuda por favor (2x-3) x (3x+5) nao to entendendo e urgente gente

Answer 1

(2x-3) x (3x+5)
(xx2x-xx3)x(3x+5)
$( x^{1+1}x2-xx3) x(3x+5)$
(x²x2-xx3)x(3x+5)
(2x²-xx3)x(3x+5)
(2x²-3x)x(3x+5)
(2x²-3x+2x²x5-3xx3x-3x-3xx5)
$( 6x^{2+1}+2 x^{2} x5-3xx3x-3xx5)$
(6x³+2x²x5-3xx3x-3xx5)
(6x³+10x²-(3x)²-3xx5)
(6x³-10x²-32x²-3xx5)
(6x³+x²-3xx5)
6x³+x²-15x
