A = 3 b = 2 c = -3 we will substitute these values into the expression
-a² - 3b³ + c² + 2b³ - c²
-(3)² - 3(2)³ + (-3)² + 2(2)³ - (-3)²
-9 - 24 + 9 + 16 - 9
-17
Answer:
No real solution
Step-by-step explanation:
First off I'm assuming that the 1 or -1 at the begging is just the problem number:
First you distribute on both sides
36 - 18x - 3 = 4 - 18x + 30
Then combine like terms
33 - 18x = 34 - 18x
Then rearrange the terms by adding 18x to both sides and subtracting both sides by 33. You should get:
0 = 1
When you add positive 18x it cancels the -18x out. And 34 - 33 is 1. Obviously, zero cannot equal 1 so there is no real solution
