X divided by 8=1.5 divided by 2<br><br> solve for "x"
Travka [436]
1. 1,5 divided by 2 is 0,75 so on the right side its 0,75

2. We make x/8 = 0,75 | *8

so we get: x = 0,75 * 8

which is the same as x = 6

so the answer is x = 6

x^2 - x/5 + 2 = 0

Subtract 2 from both sides.

x^2 - x/5 = -2

Multiply all terms by 5.

5x^2 - x = -10

Add 10 to both sides.

5x^2 - x + 10 = 0

We can now apply the quadratic formula:

-b ± \frac{\sqrt{b^2 - 4ac} }{2a}

1 ± (√ 1 - 200) / 10

1 ± √-199 / 10

1 ± i√199 / 10

<h3><u>The solutions are equal to 1 + or - i times the square root of 199 divided by 10.</u></h3>
