When you’re finishing the power of a power, you multiply (ex. (x^2•y^3)^3 will become (x^2)^3 • (y^3)^3 = x^6 • y^9
Answer:
PEMDAS
Step-by-step explanation:
Use PEMDAS. Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.
Start with your parenthesis, which is (9-6). This comes out to 3. Your equation should now look like 2+(3)x5/3
Then, go to your exponents. Since we don't have any, we skip this step.
Now, we look from left to right for any multiplication symbols or division symbols. Finding (3)x5, this comes out to 15. Now rewrite your equation, if should look like this: 2+15/3.
Repeat the last step and find your division symbol, and find this 15/3. That comes out to 5.
The last step is finding addition or subtraction symbols, and since there's only two numbers left we can just solve the problem from here.
2+5=7.
Simplify brackets
-8a - 6 - 10a - 2 + 5a
Collect like terms
(-8a - 10a + 5a) + (-6 - 2)
Simplify
<u>-13a - 8</u>
We need to put all elements in one side so that the other side is 0. Then, apply quadratic formula to solve the problem. To do that, we need to subtract both sides by 4.
