@Dbzfan836 can u help

Answer 3

is this algebra?

Answer 4

yes

Answer 5

@Broskishelleh

Answer 6

this is my bother, and an excellent algebra guy. hes a yr older than me

Answer 7

\[\frac{ z^2-3z+2 }{z^2+3z-4 }* \frac{ z^2+6z+8 }{z^2-4 }=z \]

Answer 8

forgot to put the z at the end. ok cool. thanks

Answer 9

k he is writing it out now

Answer 10

hes doin the math and is almost done

Answer 11

Answer 15

sorry and thank you

Answer 16

srry its taking so long. he was using his head for some of the calc

Answer 17

no no its completely fine

Answer 18

Factor the numerator.
(z−2)(z−1)/z2+3z−4 ⋅ z2+6z+8/z2−4=z
Factor the denominator.
(z−2)(z−1)/(z+4)(z−1) ⋅ z2+6z+8/z2−4=z
Reduce the expression by canceling out all common factors from the numerator and denominator.
z−2/z+4 ⋅ z2+6z+8/z2−4=z
Factor the numerator.
z−2/z+4 ⋅ (z+4)(z+2)/z2−4=z
Factor the denominator.
z−2/z+4 ⋅ (z+4)(z+2)/(z+2)(z−2)=z
Reduce the expression by canceling out all common factors from the numerator and denominator.
z−2/z+4 ⋅ 1(z+4)/z−2=z
Cancel the common factor of (z+4) from the denominator of the first expression and the numerator of the second expression.
(z−2) ⋅ 1/z−2=z
Reduce the expression by canceling out all common factors from the numerator and denominator.
1=z
