like this right ?

Answer 4

yes

Answer 5

yes right factor both denominator

Answer 6

do you know to factor quadratic equations ?

Answer 7

how*

Answer 8

you find two mutilply numbers that equals -10 and add up to -3

Answer 9

yep^

Answer 10

thats where i need help

Answer 11

start from 1
10 times 1 =10
5 times 2 = 10
these number you can try to factor
now change signs and see which one give you -3 when you add or subtract

-5 and 2

Answer 13

yep right so because leading coefficient is one so you can right like this
(x -5) and x-2)
now factor this x^2 +x -12

Answer 14

-3 and 4

Answer 15

yep right \[\huge\rm \frac{ x-5 }{ (x-5)(x+2) } \times \frac{ x+4 }{ (x-3)(x+4) }\]

Answer 16

now you just cross out the like terms

Answer 17
