Question

Factor 7x^2+10x+3 by splitting the middle term

Answer 1

Explanation:

7x^2 + 7x + 3x + 3

7x(x + 1) + 3(x + 1)

(7x + 3)(x + 1)

Answer 2

(7x+3)(x+1)

Explanation:

Numbers add up to 10 (middle term) and numbers multiply to get 21 (7x3)

Numbers are 7 and 3

Therefore,

`7x^(2) +7x+3x+3`

= 7x(x+1) + 3(x+1)

= (7x+3)(x+1)
