Question

Is x=-3 a solution of the equation 2x^2-7x+9=0

Answer 1

Answer:

The answer will not be -3.

Answer 2

Answer:

NO

Step-by-step explanation:

The given equation is $2x^{2}- 7x+9 = 0$.

Substitute the value of x as -3 in the equation.

$2(-3)^{2}+7(-3) + 9 =0\\ 2(9) + (-21) + 9 = 0\\18 -21+9=0\\6\neq 0$

So, x = -3  is not the solution to the equation.

The left-hand side is not equal to the right-hand side.
