The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
4
The answer is (3.5)2 plus (4)2 equals 410.
3
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
x2 + 6x + 8 = (x + 4)(x + 2)
x = 2 and x = 4
x2 + 12x + 32 = x2 + 8x + 4x + 32 = x*(x + 8) + 4*(x + 8) = (x + 8)*(x + 4)
8
8
Y=(x+8)^2-5
4+4 equals 8.
