Question

PLZ HELP!!!
What type of quadratic equation is represented in the graph below?

a)Not enough information
b)Non-factorable Trinomial
c)Perfect Square Trinomial
d)Difference of Two Squares

Answer 1

start by identifying the roots

Answer 2

what do you mean by this? :o

Answer 3

where the graph is y=0

Answer 4

i don't understand

Answer 5

y=0 is the line on the x-axis
so when the x-axis intersects with the graph is whats considered a root

Answer 6

oh so the vertex of the graph? because if so, then it is (0, -4) i think

Answer 7

i mean point (2,0) and...?

Answer 8

(-2, 0)

Answer 9

so the roots are 2 and -2,
now a quadratic equation can be written in the form of (x-a)*(x-b) where a and b are the roots

Answer 10

yes, so is the answer D?

Answer 11

yes

Answer 12

Okay thank you very much :)

Answer 13

on a side note, differences of 2 squares are always in the form of x^2-a^2 = (x-a)(x+a).
