Step-by-step explanation:

Step 1: Define

3|x + y|² - (xy)²

x = 3

y = -5

Step 2: Evaluate

Substitute:                    3|3 - 5|² - (3(-5))²Multiply:                        3|-2|² - (-15)²Exponents:                   3|-2|² - 225Absolute Value:           3(2)² - 225Exponents:                   3(4) - 225Multiply:                        12 - 225Subtract:                       -213

The final answers are:

Step-by-step explanation:

-The equation:

Use the Quadratic Formula:

-Then, you solve:

-Multiply -7 by the exponent 2:

-Multiply to the 4 and the 2:

-Distribute -4 by 8:

-Add 49 and 32 together:

-Take the square root of 81:

-The opposite of -7 is 7:

-Multiply 2 times 2:

-Add both the 7 and 9:

-Divide 16 by 4 to get 4:

So, the first answer and you need to find the second answer.

-To find the second answer, you to reduce the fraction to lowest terms and canceling out the 2:

So, the second answer is .

-The results are:
