Question

How do you simplify y2+3y−47y3+7y2−14y?

Answer 1

Answer : - 136 y

Step by step explanation :

$y \times 2 + 3y - 47y \times 3 + 7y \times 2 - 14y$

Use the commutative property to reorder the terms.

$= > 2y + 3y - 47y \times 3 + 7y \times 2 - 14y$

Calculate the product. Multiplying a negative and a positive equals a negative.

(-) ×(+) = (-)

$= > 2y + 3y - 141y + 7y \times 2 - 14y$

Calculate the product by multiplying the numbers.

$= > 2y + 3y - 141y + 14y - 14y$

Eliminate the opposites.

$= > 2y + 3y - 141y$

Collect the like terms by calculating the sum or difference of their coefficients.

$= > (2 + 3 - 141)y$

Calculate the sum or difference.

$= > - 136y$
