Question

am nevoie la 8 de la f) la k) va rog mult

Answer 1

Răspuns:

Explicație pas cu pas:

f) (2x - 1)(14x - 7) = 7(2x - 1)(2x - 1) = 7(2x - 1)^2

g) (x + 6)(10x + 5x + 30) = (x + 6)(15x + 30) = 15(x + 6)(x + 2)

h) 6(x - 3)(2x - 6 + x) = 6(x - 3)(3x - 6) = 18(x - 3)(x - 2)

i) 7(3x - 1)(3x - 3x + 1) = 7(3x - 1)

j) 8(4x + 3)(3x - 4x - 3) = 8(4x + 3)(-x - 3)

k) (2x + 5)(3x - 6 - 2x + 8 + 2) = (2x + 5)(x + 4)
