2b²+ =//b


please answer this​

Answer 1

Answer:

12x

2

−7x+1

=12x

2

−4x−3x+1

=4x(3x−1)−1(3x−1)

=(4x−1)(3x−1)

(ii) 2x

2

+7x+3

=2x

2

+6x+x+3

=2x(x+3)+1(x+3)

=(2x+1)(x+3)

(iii) 6x

2

+5x−6

=6x

2

+9x−4x−6

=3x(2x+3)−2(2x+3)

=(3x−2)(2x+3)

(iv)) 3x

2

−x−4

=3x

2

−4x+3x−4

=x(3x−4)+1(3x−4)

=(3x−4)(x+1)
