Can someone tell me if I am right?
Factor by group
20x^212x=15x9
20x^2+3x+9
(4x+3)(5x3) answer

20x^227x9

meant +9 and then do the rest.

yes, you are right, but you should have maintained your equation.
20x^2+3x+9 = 0
(4x+3)(5x3) = 0
You could have tested your answer by expanding it to get back the
20x^2+3x+9 = 0

So my second line should be:
20x^227x+9=0

Sorry, I put and = when it should have been a +! Is the one below right?
20x^212x+15x9
20x^212x+15x9
= 20x^2+3x9
= (4x+3)(5x3)
