The given equation does not have any solution.
For given question,
We have been given an equation −5a + 5a + 9 = 8
We know that the like terms are those terms which have same variable to the same power.
Combine Like terms;
0 + 9 = 8
9 = 8
⇒ which is False.
This statement is false for any values of x
Therefore, the given equation does not have any solution.

Answer:
Step-by-step explanation:
2x2−3x−4=0
For this equation: a=2, b=-3, c=-4
2x2+−3x+−4=0
Step 1: Use quadratic formula with a=2, b=-3, c=-4.
x=
−b±√b2−4ac
2a
x=
−(−3)±√(−3)2−4(2)(−4)
