Answer 1

$\huge \underline \bold \color{plum} \mathcal{HEYA }$

We can find the correct answer by putting all the values one by one in place of x in the equation. The option which yields zero is the correct answer.

In this case, by putting 1/2 in place of x, we get

$2\times( \frac{1}{2} {)}^{2} + 7 \times \frac{1}{2} - 4$

$\frac{1 + 7}{2} - 4$

$\frac{1 + 7 - 8}{2}$

$\frac{8 - 8}{2} = 0$

$\therefore \: the \: correct \: answer \: is$

$\huge \color{green}(b) \frac{1}{2}$
