What are the approximate solutions of 2x^2+9x=8 to the nearest hundredth

sveta [45]

Answer:

x=0.76 or -5.26

Step-by-step explanation:

You can apply the completing square method to solve this ;

$2x^2+9x=8\\\\$

Rewrite the equation with a zero like below

$2x^2+9x-8=0$

This is by taking 8 to the left side of the equation

Divide the terms by 2 in x²

$\frac{2x^2}{2} +\frac{9x}{2} -\frac{8}{2} =\frac{0}{2}$

$=x^2+4.5x-4=0$

Move the number term to the right side of the equation

$x^2+4.5x=4$

complete square on the lefts side of the equation, how?

$=(\frac{b^}{2})^2 =(\frac{4.5}{2} )^2=5.0625$

balance the equation by adding this value to the right side , in this form

$x^2+4.5x+5.0625=4+5.0625\\\\$

Factorize the left side

$(x+2.25)(x+2.25)=9.0625\\\\\\(x+2.25)^2=9.0625\\$

Eliminate the square on the left side

$x+2.25=\sqrt{9.0625}$

x+2.25= ± 3.010

Solve for x

x=+3.010-2.25=0.76

x=-3.010-2.25=-5.26

The expressions are simplified to 2x and $\frac{2}{(x+ 1)(x - 1)}$

<h3>How to simply the expressions</h3>

Given the expression;

$\frac{8x^2 - 4x}{4x - 2}$

Let's factorize the numerator;

$\frac{2x( 4x - 2)}{4x - 2}$

Factor the common terms, we have;

2. $\frac{1}{x-1} - \frac{2}{x} + \frac{1}{x + 1}$

Find the Lowest common multiple

$\frac{x(x+ 1) - 2 (x+ 1)(x - 1) + x(x-1)}{x(x-1)(x+ 1)}$

expand the brackets

$\frac{x^2 + x -2(x^2 -x + x -1) + x^2 -x}{x(x-1)(x+ 1)}$

$\frac{x^2+x - 2x^2 -2 + 2x + 2 + x^2 - x}{x(x+1) (x -1)}$

collect like terms

$\frac{2x}{x(x+ 1) (x-1)}$

Divide common terms

$\frac{2}{(x+ 1)(x - 1)}$

Thus, the expressions are simplified to 2x and $\frac{2}{(x+ 1)(x - 1)}$
