Step-by-step explanation:
4x2=−9x−4
Step 1: Subtract -9x-4 from both sides.
4x2−(−9x−4)=−9x−4−(−9x−4)
4x2+9x+4=0
For this equation: a=4, b=9, c=4
4x2+9x+4=0
Step 2: Use quadratic formula with a=4, b=9, c=4.

Answer:
Step-by-step explanation:
With this question, we just have to group the terms, so in this case, we can remove the common term (x - 4), and then group the rest of them
If we do that we get:
(x - 4) (2x + 7)
