Question

Solve the equations to find the value of variable "y" by using appropriate identity:
(y - 5)2 - (y - 3)2 = 12.

Answer 1

Step-by-step explanation:

(y-5)2 - (y-3) 2 = 12

2y-10-(2y-6) =12

2y-10-2y+6 =12

Answer 2

Step-by-step explanation:

=y2-10y+25 -y2-6y+9=12

=2y=12-34= -22

=y=22/12

=y=1.8
