If: x2+7x+12 = 0
Then: (x+4)(x+3) = 0
So it follows: x = -4 and x = -3

True, but that is not using the quadratic formula.
According to the quadratic formula, for the equation ax2 + bx + c = 0:
x = [-b ± sqrt(b2 - 4*a*c)]/(2*a)
= [-7 ± sqrt(72 - 4*1*12)]/(2*1)
= [-7 ± sqrt(49 - 48)]/2
= [-7 ± sqrt(1)]/2
= [-7 ± 1]/2
= [-7 -1]/2 or [-7 +1]/2
=-8/2 or -6/2
= -4 or -3
