1

Match each equation to an equivalent equation with a perfect square on one side.

Draggable itemCorresponding Item
x2 + 8x = 2
(x + 4)2 = 18
x2 - 20x = -9
(x + 5)2 = 12
x2 - 14 = 5
(x - 7)2 = 54
x2 + 10x = -13
(x + 1)2 = 1
x2 + 4x - 5 = 0
(x + 2)2 = 9
x2 + 2x = 0
(x - 10)2 = 91
1

You subtract 5 from both sides to rewrite the equation as x2 - 6x = 7. What should you add to both sides to make a perfect square?
