Question

Use a graphing calculator to solve the equation to the nearest tenth.2x^2 - 4x -10=0; x between 3 and 4

Answer 1

Given the equation:

$2x^2-4x-10=0;x\in(3,4)$

We will use a graphing calculator to solve the equation

The graph of the equation will be as shown in the following figure:

As shown the intersection between the given equation and the x-axis is a point between 3 and 4 which = 3.4495

Rounding to the nearest tenth

So, the answer will be the solution to the equation:

$x=3.4$
