x2 + 4x - 96 = (x - 8)(x + 12).
X2 + 4X - 5 = 0 what two factor of - 5 add up to 4? (X - 1)(X + 5) ----------------- ( so, X = 1 and X = - 5 )
x2+4x-32 = (x-4)(x+8) when factored
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
No.
y = x2 - 4x + 4 can be factored into y = (x-2)(x-2) The repeated factor is 2.
x3 + x2 + 4x + 4 = (x2 + 4)(x + 1)
x2 + 4x - 96 = (x - 8)(x + 12).
y = 4x-3
X2 + 4X - 5 = 0 what two factor of - 5 add up to 4? (X - 1)(X + 5) ----------------- ( so, X = 1 and X = - 5 )
x2+4x-32 = (x-4)(x+8) when factored
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
No.
x2 + 4x + 6 can not be factored. If you want, you can reduce it to an expression with a single x term by comleting the square: x2 + 4x + 6 = x2 + 4x + 4 + 2 = (x + 2)2 + 2
-3
x^2+4x+7
2x = x2 + 4x - 3 x2 + 2x - 3 = 0 (x - 1)(x - 2) = 0
