x2-64 = (x-8)(x+8)
x2 + 10x + 25 --> (x + 5)2
Um.......is it x2+6x or x2-6x. I think your missing some things here champ
If that's + 10x + 21, the answer is (x + 7)(x + 3)
x2-10x-24 = (x+2)(x-12) when factored
An equation would be....,X2 - 10X + 16 = 0easy factoring(X - 2)(X - 8)==========So.X = 2====
(x + 8)(x + 2)
X2 + 8x + 16 = 10x +16x2 + 8x + 16=2x + 8x + 16=10x + 16
x2-64 = (x-8)(x+8)
When the co-efficient of x2 is 1
-(x - 1)(x2 + x + 1)
If you mean x^2 -10x+16 then it is (x-2)(x-8) when factored
X2 - Y2 = (X + Y)(X - Y)
Rearrange: x2 - 10x + 25 = 0ie (x - 5)(x - 5) = 0x = 5Check: x2 = 25; 10x - 25 = 50 - 25 = 25. Job done
x2 - 10x + 25 = 64 Or x2 - 10x + 25 = 64? If the first, move all over to 1 side; x2 - 10x + 25 - 64 = 0 x2 - 10x + -39 = 0 Then make it into quadratic equations; (x - 13)(x + 3) = 0 Therefore x = 13 or x = -3. If the second, 8x = -39 -39/8 = -9.75 = x
(x - 8)(x - 2)
(x+5)^2 and therefore x = -5
