x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10
X2 + 8x + 16 = 10x +16x2 + 8x + 16=2x + 8x + 16=10x + 16
x2 + 9 = 10x x2 - 10x + 9 = 0. (x - 9)(x - 1) = 0. Therefore, x = 1 or 9.
x2 - 10x + 25 = 0(x - 5)(x - 5) = 0x - 5 = 0x = 5
An equation would be....,X2 - 10X + 16 = 0easy factoring(X - 2)(X - 8)==========So.X = 2====
x2+10x-24 = (x-2)(x+12)
x2+10x-336
x2+10x-24 = (x-2)(x+12) when factored
That expression can not be factored.
x2+10x+21 = (x+3)(x+7)
(x + 2)(x - 12)
Factor the polynomial x2 - 10x + 25. Enter each factor as a polynomial in descending order.
(x - 8)(x - 2)
(x+1)(x+9)
(x + 2)(x - 12)
(x - 5)(x - 5)
For a start you tell us what the expression equals....
