Thread: Factoring

im taking an online class and i just wanted to check my answers with someone...

1. (21x to the fifth - 14x to the fourth - 35xsquared) =
7xsquared (3x to the third - 2xsquared - 5)

is that all? or is there more to the answer??

2. (q squared +6q +9) =
(q+3)(q+3)

3. (t squared - 16t +64)=
(t-8) squared

and i have more...

Looks good to me, but another thing you can do with #2, is turn , to be consistent with your #3 answer if you want; but your answers look perfectly fine to me!

Thanks :]

1. (x squared -x -20) =0
x=5,-4

2. 2x squared = 7x +15
x= -3/2, 5

3. (2x +1) (x+3) = 42
x= -13/2, 3

4. (x) (x-5) = 66
x= 11, -6

1. (x squared -x -20) =0
x=5,-4

Correct!

2. 2x squared = 7x +15
x= -3/2, 5

Correct!

3. (2x +1) (x+3) = 42
x= -13/2, 3

Correct!

4. (x) (x-5) = 66
x= 11, -6

Correct!
