Quadratics by Square Roots

Directions: We can solve quadratics like equations (by solving for x) when there is no middle term.Steps to solve: 1) Isolate the squared term2) Solve for x (remember there are two answers) 1) 2x2= 72 x = -6 and 6 2) x2+ 64 = 0 no solution 3) 3x2+ 1 = 13 x = -2 and 2 4) Show your work below. 5) 3x2+ 2 = x2+ 18 Show work below. 6) -x2+ 5 = 7 no solution 7) 3x2- 5 = 22 x = -3 and 3 8) Show work below. 9) 2x2- 7 = x2+ 5 Show work below. 10) Show work below.
