2x2+11x+12 is a quadratic polynomial that is , ax2+bx+c where a=2 ,b=11 ,c=12
Multiply a to b i.e., 2*12=24 now factorise 24= 2*2*2*3
Now arrange these terms in such condition so that we could get the middle term of quadratic polynomial.
Therefor, 2*2*2 * 3 ------------ ----- 8 + 3 =11
So, 2x2 +8x+3x +12
Now take common
2x(x +4) +3 (x+4)
(X+4)(2x+3)
