x2+7x+12
x4 + 7x2 - 60 = x4 + 12x2 - 5x2 - 60 = x2(x2 + 12) - 5(x2 +12) = (x2 - 5)(x2 +12)
x2 -11x-12= (x-12)(x+1)
x2 + 13x + 12 = (x + 1)(x + 12)
No. x2 -4x - 12 = (x + 2)(x - 6)
x2 - 10x - 24= x2 - 12x + 2x - 24= x(x - 12) + 2(x - 12)= (x - 12)(x + 2)
If: x2+x = 12 Then: x2+x-12 = 0 And using the quadratic formula: x = -4 or x = 3
14
x2-7x+12 (x-3)(x-4)
x2-4x-12 = (x-6)(x+2) when factored
x2+7x+12=0 x2+7x=-12 x+Sqaure Root of 7x= 2(SQ Root Symbol)3
(x2-x-12)/(x-4) = (x+3)
