Question

factorise using factor theorem 2 x³- 3x²- 17x + 30​

Answer 1

Answer:

  2x3−3x2−17x+30

=2x3+2x2−12x−5x2−5x+30

=2x(x2+x−6)−5(x2+x−6)

=(x2+x−6)(2x−5)

=(x2+3x−2x−6)(2x−5)

=[x(x+3)−2(x+3)](2x−5)

=(x+3)(x−2)(2x−5)

Answer 2

Answer:

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

(2×x×x×x)-(3×x×x)-(17×x)+(2×3×5)

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