Question

3/4 is zero of polynomial 3x2-5

Answer 1

Answer:

3/4=0

p(o) = 3x2-5

p(3/4)= 3×3/4×2-5

p(3/4) = 9/2-5/1

p(3/4)=9-10/2

p(3/4) = 1/2

Answer 2

Step-by-step explanation:

Let us substitute

$x = \frac{3}{4} \: in \: the \: polynmial \: 3 {x}^{2} - 5 \\ =3 \times {( \frac{3}{4} )}^{2} - 5 \\ = 3 \times \frac{9}{16} - 5 = \frac{27}{16} - 5 \\ = \frac{27 - 80}{16} = \frac{53}{16} \: which \: is \: not \: equal \: to \: zero \: \\ hence \: \frac{3}{4} \: is \: not \: a \: zero \: of \: the \: given \: polynomial$
