Question

e(x)=(x+2)×(x-3)-(2x-1)la puterea 2+3x(x+2) la puterea 2​
VA ROG URGENT

Answer 1

Răspuns:

Explicație pas cu pas:

E(x) = (x+2)(x-3) - (2x-1)² + 3x(x+2)²

E(x) = x²-x-6 - 4x²+4x-1 + 3x(x²+4x+4)

E(x) = -3x²+3x-7+3x³+12x²+12x

E(x) = 3x³+9x²+15x-7

sau

E(x) = (x+2)(x-3) - (2x-1)² + 3(x+2)²

E(x) = x²-x-6-4x²+4x-1 + 3x²+12x+12

E(x) = 15x+5

E(x) = 5(3x+1)
