solve. express your answer in decimal form.
3x^2 - 5 = 46
Add 5 to each side
3x^2 = 46 + 5
3x^2 = 51
divide both sides by 3
x^2 = 17
x =
x = +/- 4.123105626

solve. express your answer in simplest radical form.
37 - y^2 = -8
subtract 37 from both sides
-y^2 = -8 - 37
-y^2 = -45
multiply both sides by -1
y^2 = 45
y =
Factor inside the radical to reveal a perfect square
y =
extract the square root of 9
y = +/-
