Question

How to solve When x = 3, 2x² – 5x + 3 =

Answer 1

To evaluate the given quadratic equation, simply replace the value of x in the equation with the given value that is 3.

`\begin{gathered} =2x^2-5x+3 \\ =2(3)^2-5(3)+3 \end{gathered}`

Then, solve.

`\begin{gathered} =2(9)-15+3 \\ =18-15+3 \\ =6 \end{gathered}`

Therefore, the value of the equation when x = 3 is 6.
