Question

What is the factored form of 4z2 – 24z + 36?

Answer 1

Find the Greatest Common Factor (GCF)

Answer 2

the GCF is 4

Answer 3

That^ is the factor that is common to all the terms :-)

Answer 4

Factor out the GCF

4(4z^2/4+-24z/4+36/4)

Simplify

Answer 5

You have to Simplify each term in parentheses
4(z^2-6z +9)

Answer 6

z^2-6z +9 fits the form a^2−2ab+b^2
Simplify using the identity

Answer 7

@skullpatrol no fair if it's off the screen ;)

Answer 8

:D

Answer 9

4(z^2 - 2(z)(3) + 3^2)

Answer 10

Use Square of Difference and simplify

Answer 11

ok

Answer 12

sorry my computer froze.

Answer 13

i am back now, so would that equal (2z + 6)(2z – 6)?

Answer 14

Nope, it's (a-)^2
which is = 4 (z-3)^2

Answer 15

oh ok

Answer 16

my options are:
(2z + 6)2

(2z – 6)2

(2z + 6)(2z – 6)

4(z + 6)(z – 6)

Answer 17

im still a bit confused @Jack1

Answer 18

none of ur answers fit the equation then, the only right ones are
4(z-3)(z-3)
or
4(z-3)^2
or
(4z-12)(z-3)
which are all just different ways of writing what nando's wrote above hey... sorry :(
