Question
Verify whether the following zeroes of the polynomial, indicated against them.
p(x) = lx + m, `x = – m/l`
Advertisements
Solution
If `x = -m/l` is a zero of polynomial p(x) = lx + m, then `p(-m/l)` should be 0.
Here, `p(-m/l) = l(-m/l)+m`
= –m + m = 0
Therefore, x = `-m/l` is a zero of the given polynomial.
