Question

Find the sum and the product for the given expression : $y^2-2y-15$.

• A. -2, 15
• B. 2, -15
• C. -2, -15
• D. 2, 15

Answer 1

The correct option is C -2, -15

Given expression: $y^2-2y-15$
By comparing the given expression with standard form: $a{x}^2+bx+c$;
we get $a=1$; $b=-2$; $c=-15$
We know that
sum = b = -2
product = $a\times c=1\times -15$
= $-15$
Hence, the correct option is "d".
