Question

How do you simplify −7y(y2−3y)?

Answer 1

Answer : 7y^2

Step by step explanation :

$- 7y(y2 - 3y)$

Use the commutative property to reorder the terms.

$= > - 7y \times (2y - 3y)$

Collect the like terms by subtracting their coefficients and calculating the difference.

$= > - 7y \times ( - y)$

Multiplying two negatives equals a positive. (-) × (-) = (+)

$= > 7y \times y$

Calculate the product

$= > 7y {}^{2}$
