Question

What is the simplified form of the quantity 4 z squared minus 16z plus 15 over the quantity 2 z squared plus z minus 15 ?

Answer 1

\[\frac{ 4z^2-16z+15 }{ 2z^2+z-15 }\]
is it yours?

Answer 2

since Calisto here, let him help. hihi... he is much more better than me

Answer 3

@DeadShot Are you here? Is the expression given by Hoa right?

Answer 4

Suppose the expression is correct. To simplify it, we need to factorize both the numerator and denominator.
Consider the numerator,
\[4z^2-16z+15\]\[=4z^2-10z-6z+15\]Take out the common factor for the first two terms and last two terms:
\[=2z(2z-5)-3(2z-5)\]Take out the common factor again, we'll get
\[=(2z-3)(2z-5)\]

Now, try to factorize the denominator.

Answer 5

\[So-the- answer -is\frac{ (2z-3) }{ (z+3) } \]right?
