# Solve : X² – (A + B)X + Ab = 0 - ICSE Class 10 - Mathematics

#### Question

Solve : x² – (a + b)x + ab = 0

#### Solution

x^2 - (a + b)x + ab = 0

=> x^2  - ax - bx + ab = 0

=> x(x - a) - b(x - 1) = 0

=> (x - 1)(x - b) = 0

since x - a =0 or x - b = 0

then x = a or x = b

Is there an error in this question or solution?
