Question

x^2-7x+12 what is answer please tell guys

​

Answer 1

Answer:

x^2+7x+12

=>x^2+3*x+4*x+12

(We have to take the factors of 12 such that the summation of the factors of 12 having a value which is equals to the coefficient of x that is 7 here.)

(since, factors of 12 are 3 and 4 )

=>x(x+3)+4(x+3)

(Taking x and 4 common from 1st-2nd and 3rd-4th term respectively)

=>(x+4)(x+3)

Therefore, factors of x are (X+4)and (x+3).
