Question

1)
Solve the quadratic equation by completing following activity.
y2 + y = 2​

Answer 1

Answer:

Step-by-step explanation:

y²+y=2

y²+y-2=0

By midterm splitting,

y²+2y-y-2=0

y(y+2)-1(y+2)=0

(y+2)(y-1)=0

So, y+2=0

y=-2 &

y-1=0

y=1

Hope it was helpful!!

Answer 2

Answer:

1 and -2

Step-by-step explanation:

y²+y = 2

y²+y-2 = 0

y²+2y-y-2 = 0

y(y+2)-1(y+2) = 0

(y-1)(y+2) = 0

y-1 = 0 ; y+2 = 0

y=1 ; y = -2
