How do you factorise x3 plus 2x2-8x plus 5 equals 0?
x3 + 2x2 - 8x + 5 = 0 x(2x - 8) + 5 = 0
8x plus 32 plus 24 equals 0?
8x + 32 + 24 = 0 So 8x + 56 = 0 Subtract 56 from both sides: 8x = -56 Divide both sides by 8: x = -7
What is the answer to 8x plus 8 equals 9x-18 plus 9?
8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:
What is the x intercept values of equation y equals -16x2 plus 342?
y = -16x2 + 342At the x-intercepts, y=0-16x2 + 342 = 016x2 = 342x2 = 342/16 = 21.375x = plus and minus sqrt(21.375) = approx. plus and minus 4.6233 (rounded)
X2 - 8x plus 16 equals 0?
x*x - 8x +16 = 0 x*x = 8x + 16 x - 16 = _/8x x_/-4 = 2 x = 2
What is the x value of -8x plus 8x plus 4 equals -24?
- 8x + 8x = 0 so question is meaningless.
X2-8x plus 32 equals 0?
no

How do you solve 16x2 - 24x plus 7 equals 0?
If you can't factor it easily, use the quadratic formula.
-8x plus 5y equals 10?
x=0 y=2
X2 - 8x plus 16 equals 0?
x*x - 8x +16 = 0 x*x = 8x + 16 x - 16 = _/8x x_/-4 = 2 x = 2
-4x2 plus y2-8x-12y plus 36 equals 0?
dont know sorry
