1, then A + BC =?​

Answer 1

Question

If A = x+y + 2, B = x + 1, C = y-

1, then A + BC =?​

to find: A+BC

SOLUTION

• A+BC
• x+y+2+(x+1)(y-1)
• x+y+2 + xy-1x+1y-1

• 2+xy-1

hence required answer is

2+xy-1

Answer 2

GIVEN:

• A = x+y + 2
• B = x + 1

• C = y- 1

TO FIND:

• A + BC =?​

SOLUTION:

BC = (x + 1) (y - 1)

     = xy - x + y - 1

 A + BC = x + y + 2 + xy - x + y - 1

              = 2y + xy + 1

Therefore, the value of A + BC = 2y + xy + 1
