Question

Factorise the polynomial -
10x^2 − 9x + 2

Answer 1

Answer:

(5x−2)(2x−1)

Step-by-step explanation:

Factor 10x2−9x+2

10x2−9x+2

=(5x−2)(2x−1)

Answer:

(5x−2)(2x−1)

Answer 2

Answer:

=(2x-1)(5x-2)

Step-by-step explanation:

Factorising trinomials:

10x^2 − 9x + 2

5*4= 20, (-5) +( - 4) = 9

=10x^2-5x-4x+2

Grouping terms

=(10x^2-5x)-(4x-2)

Taking common factors

=5x(2x-1)-2(2x-1)

=(2x-1)(5x-2)
