y^2+7=(y-1)^2+3y

Solution

y^{2} + 7 = (y - 1)^{2} + 3 y

Solution

y = 6

Solution steps

y^{2} + 7 = (y - 1)^{2} + 3 y

Expand

(y - 1)^{2} + 3 y : y^{2} + y + 1

y^{2} + 7 = y^{2} + y + 1

Move

7

to the right side

y^{2} = y^{2} + y - 6

Subtract

y^{2} + y

from both sides

y^{2} - (y^{2} + y) = y^{2} + y - 6 - (y^{2} + y)

Simplify

- y = - 6

Divide both sides by

- 1

y = 6
