Question

Fatore:
x³-5x²+4x-20
2x³+x²-6x-3x
14yz-28zx+6y-12x
(36a²-4)

Answer 1

Fatore:

x³-5x²+4x-20

x²(x - 5) + 4(x - 5)

(x - 5)(x² + 4)

2x³+x²-6x-3x ARRUMA a casa!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

2x³ - 6x + x² - 3x

2x²(x - 3) + x(x - 3)

(x - 3)(2x² + x)

14yz-28zx+6y-12x

14z(y -2x) + 6(y - 2x)

(y - 2x)(14z + 6)

(36a²-4)

(6a - 2)(6a + 2)
