Question

What is the simplified form of the quantity 4 x squared plus 20x plus 25 over the quantity 2x plus 5 ?

Answer 1

can you factorise the
\[4x ^{2} + 20x + 5\]

Answer 2

(2x+4)(2x+5)?

Answer 3

no
it's (2x+5)(2x+5)

Answer 4

yh that is right!

Answer 5

so if you replace what you have with the initial, what do you get???

Answer 6

\[\frac{ (2x+5)(2x+5) }{ (2x+5) }\]right?

Answer 7

can you see that one of the (2x + 5) would cancel out the other one below???

Answer 8

so now what do you get??

Answer 9

(2x+5)

Answer 10

so that is the answer! :)

Answer 11

So the answer is (2x + 5), with the restriction x ≠ five over 2 right?

Answer 12

i do not think there is a restriction in this one...

Answer 13

it satisfies all real numbers!

Answer 14

Okay, Thanks!

Answer 15

you are welcome! :)
