Answer 1

Step-by-step explanation:

1.x^2+7x+12

find two numbers that multiply to give the constant by the coefficient of x squared and when added will give you 7 x . the numbers are 3 and 4

(x^2+4x)+(3x+12)

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

(x+4) and(x+3) are the factors

2.4x^2+6x+2

(4x^2+2x)+(4x+2)

2x(x+1)+2(x+1)

(x+1) and(2x+2) are the factors.

Answer 2

Step-by-step explanation:

x2 + 7x + 12

x2 + 4x + 3x + 12

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

(x + 3) and (x + 4) are the factors

4x2 + 6x + 2

4x2 + 4x + 2x + 2

4x (x + 1) + 2(x + 1)

(x + 1) and (4x + 2) are the factors
