Question

Factorise: x² + 7x + 12 using middle term splitting method​

Answer 1

Answer:

x² + 7x + 12= x^2 +3x+4x+12. =. x(x+3) + 4(x+3). = (x+3)(x+4)

Answer 2

Step-by-step explanation:

factors of 12 which add up to 7 are (4 & 3)

4+3=7, (4)(3)=12.

x^2 + 4x + 3x + 12

taking x as common,

x(x + 4) + 3(x+4)

(x+3)(x+4).

therefore the answer is (x+3)(x+4) by splitting the middle term.

Hope it helps!
