Unit 4 Lesson 1: Completing the square Advanced Math Topics Mrs. Mongold

Solve x2 – 50 = 0

Solve 2x2 = 14

Solve (x+1)2 = 12

Solve (2x – 5)2 = -16

Solve p2 + 3p = 4

Trinomial that isn’t factorable… Move the constant back over p2 + 2p+ = 4+

Trinomial that isn’t factorable… Move the constant back over p2 + 2p+ = 4+ Divide the middle term (x term) by 2 2/2 = 1

Trinomial that isn’t factorable… Move the constant back over p2 + 2p+ = 4+ Divide the middle term (x term) by 2 2/2 = 1 Add answer2 to BOTH sides of the equation p2 + 2p + 1 = 4 + 1

Trinomial that isn’t factorable… Move the constant back over p2 + 2p+ = 4+ Divide the middle term (x term) by 2 2/2 = 1 Add answer2 to BOTH sides of the equation p2 + 2p + 1 = 4 + 1 Factor the left side (p + 1)2 = 5

Trinomial that isn’t factorable… Move the constant back over p2 + 2p+ = 4+ Divide the middle term (x term) by 2 2/2 = 1 Add answer2 to BOTH sides of the equation p2 + 2p + 1 = 4 + 1 Factor the left side (p + 1)2 = 5 Square root both sides and solve

Solve m2 – 7m -1 = 0

Solve 2x2 – 8x + 3 = 0

Solve 3x2 – 9x + 8 = 0
