Problems for Unit 8 Algebra 21). Use Factoring to Solve the equation:
X^2+7x+10=0
6x^3-216x=0
9x^2+45x=0
2y^2-162=0
X^2-15x+36=0
5z^2=55z-140
2) Write the equation x(x-14) +45=0 in quadratic form and then solve it by factoring.
3) Write the equation 4x(x-17) = -280 in quadratic form and then solve it by factoring.
4) Use the square root property to solve the equation:
(X-7)^2=25
X^2+18x+77=0
5) A rectangle is 1 feet longer than it is wide and its area is 72 square feet. Find the dimensions.
6) Use the quadratic formula to solve:
