Algebra 2 - Quadratics Review

Find the Vertex

100

Find the vertex. y = -3(x+2)² - 10

(-2, -10)

200

Find the vertex. y=x²+10x+16

(-5, -9)

300

Find the vertex. y-5=4x²+8x-3

(-1, -2)

400

Find the vertex. y=-7x²-15x+21

(1.07, 29.04)

500

Write in vertex form:

2x²+12x+22

y=2(x+3)²+4

Factoring

100

Solve by Factoring: 0=x²+7x+12

(x+3)(x+4) ==> x = -3, -4

200

Solve by factoring. y=25x² - 36

(5x+6)(5x-6) ==> x=6/5 , -6/5

300

Solve by factoring: 3x²+10x-5=3

(3x-2)(x+4) ===>2/3, -4

400

Factor completely y=12x²-27

3(2x-3)(2x+3)

500

Solve by Factoring. 6x²-39x-45=0

3(2x-15)(x+1) ====> (x= 15/2, -1)
