Question

What is the quotient of

y-5\sqrt{2y^2-7y-15}
A. 2y + 3
B. 2y − 3
C. 2y − 17y R −70
D. 2y − 17y R 70

Answer 1

I think its A

Explanation:

Answer 2

None of these

Explanation:

y-5\√(2y2 - 7y -15)

On simplifying 2y2 - 7y -15, we get

2y2 – (10-3)y -15

= 2y2 – 10y -3y-15

= 2y(y-5)-3(y-5)

= (2y-3)(y-5)

On squaring nominator and denominator we get

(y-5)2/(2y-3)(y-5)

= (y-5)/(2y-3)

So the quotient becomes, 5/2

While the remainder becomes 2.5
