Question

Simplify -6 + 4a²+ 2b² - 7xz - 3xz + 4a²- 5b²- 2.

hint Hint:

Group the like terms.
○ Like terms are those whose coefficients are the same.
○ Perform basic arithmetic operations on like terms.

The correct answer is: Hence, the other term is 8a2 - 3b2 - 10xz - 8.

Answer:

Step by step explanation:

○        Given:
Expression: -6 + 4a²+ 2b² - 7xz - 3xz + 4a²- 5b²- 2.
○        Step 1:
○        Group like terms.
$rightwards double arrow$ -6 + 4a²+ 2b² - 7xz - 3xz + 4a²- 5b²- 2
$rightwards double arrow$ ( -6 - 2) + (4a²+ 4a²) - (7xz + 3xz) + (2b² - 5b²)
$rightwards double arrow$ ( -8) + (8a²) - (10xz ) + (- 3b²)
$rightwards double arrow$ 8a²- 3b² - 10xz - 8

Final Answer:

Hence, the other term is 8a²- 3b² - 10xz - 8.
