Question

What should be subtracted from the sum of y2 + 2y +1 and y2 + 6y - 2 to get 1?

Answer 1

Answer:

2y²+8y-2

Step-by-step explanation:

sum of y² + 2y + 1 and y² + 6y - 2 is

2y²+8y-1

Now,

let the req. no. be x

then, accor. to ques.

(2y²+8y-1) - x = 1

x = (2y²+8y-1) - 1

x= 2y²+8y-2

Answer 2

Step-by-step explanation:

you have to sub same to it accept 1

(1) (y2 +2y+1)+(-y2+2y)

=1

(2) (y2+6y-2)+(-y2+6y-1)

=1
