Question

Simplify:

y2(4y+7n2+2)−3y2(−y+8)
A 7n2y2+7y3+22y2
B 4y3+7n2y2+26y2
C 7y3+7n2y2−22y2
D −22y2+7n2y2+7y3

Answer 1

The answer to your question is letter C. 7y³ + 7n²y² - 22y²

Explanation:

y²(4y + 7n² + 2) - 3y² (-y + 8)

Multiply

4y³ + 7n²y² + 2y² + 3y³ - 24y²

Use the associative property for like terms

(4y³ + 3y³) + (2y² - 24y²) + 7n²y²

Simplify like terms

7y³ - 22y² + 7n²y² or 7y³ + 7n²y² - 22y²
