Question

3x^2+7x+4 by splitting middle term

Answer 1

Answer:

Pq = 3 × 4 = 12

so it should be written in the form in which if we multiply we get 12 and if we add it we should get as 7

12 = 3 × 4 and if we add 3 and 4 we get 7

= 3x² + 3x + 4x +4

= 3x ( x + 1 ) + 4 ( x +1 ) [by taking common no. in the equation form so]

= ( 3x + 4 ) ( x + 1 )
