Divide both sides of the equation by x: x2 = 9x x2 / x = 9x / x x = 9
x2 - 8x + 32 = 0 (assuming)you can factor or use the quadratic equation.I recommend the quadratic equation.
X2 = k Take square root each side. X = (+/-) sqrt(k) ============
x2+3x+2=0 (x+2)(x+1)=0 x=-2 or -1

The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
do you mean, x2 = n?? Take the square root.
You cannot, in general, solve one equation with two unknown variables. x - y = x - x2 Subtract x from both sides: - y = - x2 Change signs: y = x2 And that is as far as you can go.
X(X2 - X)
(2x)ysquared
Divide both sides of the equation by x: x2 = 9x x2 / x = 9x / x x = 9
Take the square root of both sides of the equation
You will need to use the FOIL formula to solve this type of equation.
An equation demonstrates the equality of two expressions. x2+12x+13 is only one expression. For example, x+y : expression, not equation x+5 = 3 : equation
To solve this question we would need to know if you are adding or subtracting. Unless the equation is set up to equal 360 then the equation has no rationale answer.
