# Show That X-2 is a Factor of 5x^2+15x-50 - ICSE Class 10 - Mathematics

#### Question

show that

x-2 is a factor of 5x^2+15x-50

#### Solution

(x – a) is a factor of a polynomial f(x) if the remainder, when f(x) is divided by (x – a), is 0, i.e., if f(a) = 0.

f(x)=5x^2+15x-50

f(2)=5(2)^2+15(2)-50=20+30-50=0

Hence, x-2 is a factor of 5x^2+15x-50

Is there an error in this question or solution?
