Yes

Vedclass · Answer

(A) To verify if $x = -\frac{m}{l}$ is a zero of the polynomial $p(x) = lx + m$,we substitute the value of $x$ into the polynomial.$p\left(-\frac{m}{l}\right) = l\left(-\frac{m}{l}\right) + m$$p\left(-\frac{m}{l}\right) = -m + m$$p\left(-\frac{m}{l}\right) = 0$Since the value of the polynomial at $x = -\frac{m}{l}$ is $0$,it is confirmed that $x = -\frac{m}{l}$ is a zero of the given polynomial.

Verify whether the following is a zero of the polynomial indicated against it:
$p(x) = lx + m, \, x = -\frac{m}{l}$
