Homework 17 (due 4/15)

Recall: to solve an equation means to find all solutions, i.e. all numbers x that make the equality true.

Solve the following quadratic equations over the set of real numbers (i.e. find all real solutions of these equations). Show all steps of your solutions.

• x²+2x-35=0
• 2x²+7x-4=0
• 3x²-4x-5=0
• 2x²-5x+7=0
• (x+2)(x-5)=6
• x(x-3)=(2x+1)(x+2)-8
