Simplify: 18q2−45q+25/9q2−25.
Svet_ta [14]

Answer:

\frac{(6q-5)}{(3q+5)}

Step-by-step explanation:

Given: \frac{18q^{2}-45q+25 }{9q^{2}-25 }

Factorizing the numerator and the denominator, we have:

18q^{2} - 45q + 25 = 18q^{2} - 30q - 15q + 25

                         = (3q - 5)(6q - 5)

and

9q^{2} - 25 = (3q - 5)(3q + 5)

So that,

\frac{18q^{2}-45q+25 }{9q^{2}-25 } = \frac{(3q-5)(6q-5)}{(3q-5)(3q+5)}

                 = \frac{(6q-5)}{(3q+5)}

Therefore,

\frac{18q^{2}-45q+25 }{9q^{2}-25 } = \frac{(6q-5)}{(3q+5)}

5b^2-5b-8b+4+24b^2-1-13b^2-b
nexus9112 [7]

Answer:

The answer would be 16b^2 - 14b + 3

Step-by-step explanation:

In order to find this, we simply need to group the terms by their variable values. We will start with the b^2 terms.

5b^2 + 24b^2 - 13b^2 = 16b^2

Now we can use all of the b terms.

-5b - 8b - b = -14b

And finally, we'll do all the constants.

4 - 1 = 3

Using all three of these together will give us the simplified form.
