Solve, using the quadratic formula, the equation x^2 +2x=35
suppose you have a general quadratic equation in the form ax2 + bx + c = 0, then the solutions to this quadratic equation can be found by the equation x = (-b +/- (b2-4ac)1/2
solve two variables quadratic equation system 2x-y=1 10x^2-y^2-x+1=0
To solve the equation, we need to try to make the second equation all in x first.From the first equation 2x-y=1,we could rewrite it into y=2x-1,Then we put y=2x-1 into the quadratic equation 10x2
