all real solutions

Once you can accomplish arranging to get ax

^{2}+bx +c = 0...you can use the Quadratic Equation: [-b +/- sqrt(b

^{2}^{ }- 4ac)] / (2a) to solve for x= [-7 +/- sqrt[49 - 4(2)(-9)] / (2(2)

= [-7 +/- sqrt[49-(-72)] / 4

= [-7 +/- sqrt(121)]/ 4

= -7/4 +/- 11/4

x = 1 and x = -9/2
