25x^2 − 144
(5x - 12) (5x + 12)
3x+50+6x-10=180
I combined the two equations and now you can solve for x
start by adding 3x plus 6x and subtracting 10 from 50 and you get a new equation
9x +40 =180
now from here you should be able to do the rest
just subtract 40 from 180 to get 9x=140
and what is 140 divided by 9
Answer:
-4 and 6
