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

or

x=-3.010-2.25=-5.26

4.44 4.044 greater or less

Ira Lisetskai [31]

If I understand correctly, you want to know which of the two numbers is bigger?

You have to compare the numbers left to right. So: they both have 4 in the last place before the point. After that, in the place equivalent to 0.10 the number of the left has a higher digit: 4, so this number is bigger.

The asnwer is

4.44 >4.044
