Answer:

12x^2-7x+1=0

12x^2-4x+3x+1=0

4x(3x+1)+1(3x+1)=0

3x+1=0,4x+1=0

3x=-1,4x=-1

x=-1/3,-1/4

2x^2+7x+3=0

2x^2+6x+1x+3=0

2x(x+3)+1(x+3)=0

x+3=0,2x+1=0

x=-3,-1/2

Step-by-step explanation:

hey!!

Factorise:

(i) 12x2−7x−1

(ii) 2x2+7x+3

(iii) 6x2+5x−6

(iv) 3x2−x−4

ANSWER

(i) 12x2−7x+1

=12x2−4x−3x+1

=4x(3x−1)−1(3x−1)

=(4x−1)(3x−1)

(ii) 2x2+7x+3

=2x2+6x+x+3

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

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

(iii) 6x2+5x−6

=6x2+9x−4x−6

=3x(2x+3)−2(2x+3)

3)−2(2x+3)

=(3x−2)(2x+3)

(iv)) 3x2−x−4

=3x2−4x+3x−4

=x(3x−4)+1(3x−4)

=(3x−4)(x+1)

hope, this will help u ....♥️♥️
