Question

What should be the value of 'a' if y²+y-a equals to 3 for y=1

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Given:

Equation is y² + y – a = 3

The value of y is 1.

To find:

The value of a.

Solution:

It is given that,

y²+ y- a = 3 (equation 1)

Since the value of y is 1. Therefore,  

On putting y = 1 in equation 1, we get,

(1)² + 1 – a =3

a = 2 – 3

a = -1

Therefore, the value of a is equal to -1.
