2x^2-3x-2=0 \\
2x^2-4x+x-2=0 \\
2x(x-2)+1(x-2)=0 \\
(2x+1)(x-2)=0 \\
2x+1=0 \ \lor \ x-2=0 \\
2x=-1 \ \lor \ x=2 \\
x=-\frac{1}{2} \ \lor \ x=2 \\
\boxed{x=-\frac{1}{2} \hbox{ or } x=2}

2x² - 3x - 2 = 0
x = <u>-(-3) +/- √((-3)² - 4(2)(-2))</u>
                     2(2)
x = <u>3 +/- √(9 + 16)</u>
                 4
x = <u>3 +/- √(25)
</u>             4<u>
</u>x = <u>3 +/- 5
</u>          4
x = <u>3 + 5</u>  or  x = <u>3 - 5</u>
         4                   4
x = <u>8</u>             x = <u>-2</u>
      4                    4
x = 2             x = ⁻¹/₂

What is 1000 k = to but it has to be a gram .any get it cause I don't help me
denpristay [2]
You need to convert 1000kg to grams? There are 1000g\frac{1000g}{kg}
Now what you need to do is multiply the number of kg you have by your conversion fractions, making sure that grams is on top so you end up with grams in your answer:\frac{1000kg}{g} * \frac{1000g}{kg}

Kg cancel, and you are left with 1,000,000g
This means that there are 1,000,000g in 1000kg
Hope this helps!
