Ex 2.2, 3 Verify whether the following are zeroes of the polynomial, indicated against them. (vi) p(x) = lx + m , x = – π‘š/𝑙 Given p(x) = lx + m Putting x = (βˆ’π‘š)/𝑙 p ((βˆ’π‘š)/𝑙) = l ((βˆ’π‘š)/𝑙) + m = -m + m = 0 Since p ((βˆ’π‘š)/𝑙) is equal to 0 Therefore, x = βˆ’π‘š/𝑙 is a zero of the given polynomial.
