Find the roots of the parabola given by the following equation <br> 2x^2+5X-9=2x

natta225 [31]

Answer:

$x=-3\:or\:x=\frac{3}{2}$

Step-by-step explanation:

The given parabola has equation

$2x^2+5x-9=2x$

We rewrite in standard form to obtain:

$2x^2+5x-2x-9=0$

$2x^2+3x-9=0$

Split the middle terms to get:

$2x^2+6x-3x-9=0$

Factor by grouping:

$2x(x+3)-3(x+3)=0$

$(x+3)(2x-3)=0$

$x=-3\:or\:x=\frac{3}{2}$

5 = 1 and 5 in a fraction and w

vovangra [49]

What we want to do first is isolate the variable. To do this we need to multiply each side by 5 to remove the fraction

5 * 5 = 5* $\frac{1}{5}$ w
Simplify the right side
5 * $\frac{1}{5}$ w = 1w
Now simplify the left side
5 * 5 = 25
Then we get...
25 = w

There's your answer!
