x2 + 8x + 15 = (x + 3) (x + 5).
x + 4
-6
(x - 4)(x - 4)
(x + 6)(x + 2)
x2 + 8x + 15 = (x + 3)(x + 5)
x2 + 8x + 15 = (x + 3) (x + 5).
That does not factor neatly.
x + 4
x2-8x+15 = (x-3)(x-5)
x2 + 8x + 12 = (x + 6) (x + 2)
(x + 6)(x + 2)
x2 - 8x + 32 = 0 (assuming)you can factor or use the quadratic equation.I recommend the quadratic equation.
No because the discriminant is less than zero.
(x-4)(x-4)
X2 + 8x + 16 = 10x +16x2 + 8x + 16=2x + 8x + 16=10x + 16
