Solve the equation
2(y^2-66)= -13y
:
2y^2 - 132 = -13y
:
2y^2 + 13y - 132 = 0
:
Factors to:
(2x - 11)(x + 12) = 0
:
2x = 11
x = 5.5
and
x = -12
:
:
Check solution in original equation:
x = 5.5
Solve the equation
2(5.5^2-66)= -13(5.5)
2(30.25 - 66) = -71.5
2(-35.75) = -71.5
:
you can check the x = -12 solution
