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.
