x2 - 8x + 32 = 0 (assuming)you can factor or use the quadratic equation.I recommend the quadratic equation.
x² + 8x - 48 = (x + 12)(x - 4) x² + 8x + 48 = (4+(√32)i)(4-(√32)i)
Simplifying 8x2 + -8x + -16 Factor out the Greatest Common Factor (GCF), '8'. 8(x2 + -1x + -2) Factor a trinomial. 8((-x + -1)(-x + 2)) Final result: 8(x - 2)(x + 1)
x2 + 8x - 5 = 0 ∴ x2 + 8x + 16 = 21 ∴ (x + 4)2 = 21 ∴ x + 4 = ± √21 ∴ x = -4 ± √21
x - x2 - 9x + 14 = 0 ; whence, x2 + 8x = 14 , x2 + 8x + 16 = 30 , and x + 4 = ±√30 . Therefore, x = ±√30 - 4 .
x2 + 8x + 12 = (x + 6) (x + 2)
(x + 6)(x + 2)
x2 + 8x = x(x+8)
x2-8x+12 = (x-2)(x-6) when factored
-6
That does not factor neatly.
x2 + 8x + 15 = (x + 3)(x + 5)
x2-8x+15 = (x-3)(x-5)
x2 + 8x + 15 = (x + 3) (x + 5).
x^2 - 8z - 48 Factor ( x - 12)(x + 4)
4x(x2 - 2)
(x + 6)(x + 2)
