☸ Required Answer is ⬇ ⬇⬇ ⬇
⭕ (i) 12x²-7x+1
by factorisation method,
▶ 12x²-4x-3x+1
▶ 4x ( 3x-1) -1 (3x+1)
▶ (4x-1) (3x-1)
▶ 4x-1=0. or 3x-1= 0
▶ x = 1/4. or. x = 1/3
⭕ (ii) 2x²+7x+3
by factorisation method,
▶ 2x²+6x+x+3
▶ 2x (x+3) +1 (x+3)
▶ (2x+1) (x+3)
▶ 2x+1 =0 or. x+3 =0
x = -1/2. or. x = -3

12x sq - 7x+1
Splitting middle terms
12x sq - 4x+3x +1
4x(3x-1)+1(3x-1)
(4x+1)(3x-1)
2. 2x sq+7x +3
Splitting middle term
2x sq + 6x+x+3
2x(x+3)+1(x+3)
(2x+1)(x+3)
Hope it will help you
