432 = (b + 18) (b - 18)

b = 18577, b = - 18577

Decimal Notation

b = 432.37483 \dots, b = - 432.37483 \dots

Solution steps

432 = (b + 18) (b - 18)

Square both sides:

186624 = b^{2} - 324

186624 = b^{2} - 324

Solve

186624 = b^{2} - 324 : b = 18577, b = - 18577

b = 18577, b = - 18577

Verify Solutions:

b = 18577

True

, b = - 18577

True

The solutions are

b = 18577, b = - 18577

x + x = 272

x + x = 240

a (x) = x + 36

x + 1 + 1 = x - 40

2 x + 24 = x
