Question

Factorise :
(ii) 2x2 + 7x + 3
(i) 12x2 – 7x + 1
(iii) 6x2 + 5x - 6
(iv) 3x2 – X – 4​

Answer 1

i) 12ײ-7×+1

=12ײ-4×-3×+1

=-4×(-3×+1)+1(-3×+1)

=(-4×+1)(-3×+1)

ii)2ײ+7×+3

=2ײ+6×+1×+3

=2×(1×+3)+1(1×+3)

=(2×+1)(1×+3)

iii)6ײ+5×-6

=6ײ+9×-4×-6

=3×(2×+3)-2(2×+3)

=(3×-2)(2×+3)

iv)3ײ-×-4

=3ײ-4×+3×-4

=×(3×-4)+1(3×-4)

=(3×-4)(×+1)

here is ur ans. pls mark as brilliant: )
