Question

factorise 2x cube minus 3 x square - 17 X + 30​

Answer 1

Answer:

Step-by-step explanation:

2x^3 - 3x^2 - 17x + 30

= 2x^3 - 4x^2 +x^2 -2x - 15x + 30

=2x^2(x-2) +x(x-2) -15(x-2)

=(x-2)(2x^2 +x -15)

=(x-2)(2x^2 +6x -5x -15)

=(x-2)(2x(x+3) -5(x+3))

=(x-2)(x+3)(2x-5)

Answer 2

2x^3 - 3x^2 - 17x + 30

= 2x^3 - 4x^2 +x^2 -2x - 15x + 30

=2x^2(x-2) +x(x-2) -15(x-2)

=(x-2)(2x^2 +x -15)

=(x-2)(2x^2 +6x -5x -15)

=(x-2)(2x(x+3) -5(x+3))

=(x-2)(x+3)(2x-5)
