Answer:

Step-by-step explanation:
4x^2+ 12x = 135
D=b²−4ac=122−4(4)(−135)=144+2160=2304=48²

First, you replace x with -3.
It will look like -3/3.
Then you divide and get -1.
You would change the denominator and get the lowest common denominator. Thos would be 30. You would do 11/6 x 5/5 = 55/30. Then do 3/5 x 6/6 = 18/30. Then add 55/30 + 18/30 = 73/30 and simplify.
Answer:
