Solve each equation by factoring.
2x2+x=0
0, -1/2
x2=36
6,-6
The value for "b" of the quadratic function y=2x2 + 5
What is zero?
How many solutions does 0=x2+4 have?
none
n2 + 12n = -36
-6
4x2 + 25 = 125
x= 5 or x = -5
The vertex of the quadratic function y = 5x2 + 10x - 2 is a (maximum or minimum) point.
What is minimum?
What shape is a quadratic function?
Parabola
p2 + 2p - 10 = 5
-5, 3
(4x + 1)2 - 16 = 0
x = 3/4 or x = -5/4
What is the vertex of the function?
f(x) = -(x+3)2+7
(-3,7)
The "a", "b" and "c" of the quadratic function
y= 1 - 2x2 + 3x
What is a=-2, b=3 and c=1?
x2-25=0
-5,5
34 = (a - 2)2 - 2
a = 8 or a = -4
Order the following quadratic functions from narrowest to widest:
y=4x2 y=-12x2 y=11x2 y=-2x2
What is y=-12x2, y=11x2, y=4x2, y=-2x2?
Rewrite in factored form:
f(x) = x2+7x+10
1/81 - 49x2 = 0
1/63, -1/63
0 = 3(x + 7)2 - 24
x = -7 + 2 square root of 2
or
x = -7 - 2 square root of 2
If a quadratic function has a root (x-intercept) at (-3,0) and a maximum at (2,5), then what is the other root?
What is x=7?
The coordinates of the y-intercept for the quadratic function y=3x2 + 2x
What is (0,0)?
