1.	Verify whether the following are zeroes of the polynomial, indicated against them(i) p(x)=3 x+1, x=-\frac{1}{3} \quad \text { (ii) } p(x)=5 x-\pi, x=\frac{4}{5}
Answer» put x = -1/3 in p(x) i) p(-1/3) = 3×(-1)/3 + 1 = 0Yes, -1/3 is zero of polynomial p(x) ii) p(4/5) = 5x - pi 5×(4/5) - pi = 4 - piNo x = 4/5 is not a zero of polynomial

Verify whether the following are zeroes of the polynomial, indicated against them(i) p(x)=3 x+1, x=-\frac{1}{3} \quad \text { (ii) } p(x)=5 x-\pi, x=\frac{4}{5}

Answer»

put x = -1/3 in p(x)

i) p(-1/3) = 3×(-1)/3 + 1 = 0Yes, -1/3 is zero of polynomial p(x)

ii) p(4/5) = 5x - pi 5×(4/5) - pi = 4 - piNo x = 4/5 is not a zero of polynomial
