(x + 3)(x + 4)
x = -3, -4
Check it.
9 - 21 + 12 = 0
16 - 28 + 12 = 0
It checks.
7x
The three terms are 3x2, 7x and 1
(-7x + 3)(-7x +3)
4x + 8 + 7x + 12 = 11x + 20
(2x - 1)(x + 4)
7x
The three terms are 3x2, 7x and 1
4x2 + 14x + 12 = 2(2x2 + 7x + 6) = 2(2x + 3)(x + 2)
(-7x + 3)(-7x +3)
x2+7x+12
7x2-10x+3=0 (7x-3)(x-1)=0
what is 7x to the third power + 6x to the second - 2
4x + 8 + 7x + 12 = 11x + 20
x2+7x+12=0 x2+7x=-12 x+Sqaure Root of 7x= 2(SQ Root Symbol)3
(2x - 1)(x + 4)
x^2 +7x+12 = (x+3)(x+4) when factored
Answer : 12
