Question

x = 2 is not a root of the equation $2x^2–7x–5=0$.

• A. True
• B. False

Answer 1

The correct option is A

True

Substitute the value of x in the quadratic equation, $2x^2–7x–5=0$.

$\Rightarrow$ $2\left(2^2\right)-7\left(2\right)-5$

8 - 14 - 5 = -11

Hence, 2 is not a root of the given quadratic equation.
