Question

Verify whether the following zeroes of the polynomial, indicated against them.

p(x) = lx + m, `x = – m/l`

Answer 1

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.
