Factor Frenzy
Factor:
x2-9x+20
x2-9x+20 = (x-4)(x-5)
Write in standard form:
y = (x+3)(x+7)
(x+3)(x+7) = x2+10x+21
Given: h(x) = -(x-2)2 + 4
Find the vertex.
vertex: (2, 4)

Factor:
x2+2x-35
x2+2x-35= (x-5)(x+7)
Write in standard form:
y = (2x+3)(x-3)
(2x+3)(x-3) = 2x2-3x-9
Given: g(x) = 2x(x-9),
Find the x-intercept(s).
x-intercept(s): (0, 0) (9, 0)

Factor:
8x2+2x-3
8x2+2x-3 = (2x-1)(4x+3)
Write in standard form:
y = 2(3x+3)(x+4)
2(3x+3)(x+4) = 6x2+30x+24
Given: y = 2(x-3)2 - 32
Find the x-intercept(s).
x-intercept(s): (-1, 0) (7, 0)

Factor:
9x2-25
9x2-25 = (3x-5)(3x+5)
Write in standard form:
y = -(6x+2)(2x+8)
