Question

(y+5) (y-3) answer to my question only if you know​

Answer 1

(y + 5) (y - 3)

y² - 3y + 5y-15

y² + 2y - 15

Answer 2

Given:

(y + 5) (y - 3)

To Find:

Expand

Explanation

When a question is given without an equal sign, you are expected to either expand it or the factorise it. You are not supposed to assume that the equation is equal to zero and solve it.

In this case, the question is given in the factorised form, so we will expand it.

Solution

(y + 5) (y - 3) = y(y - 3) + 5(y - 3)

(y + 5) (y - 3) = y² - 3y + 5y - 15

(y + 5) (y - 3) =  y² + 2y - 15

Answer: y² + 2y - 15
