Distance from a point to a line (Coordinate Geometry)

Method 1: When the line is vertical or horizontal , the distance from a point to a vertical or horizontal line can be found by the simple difference of coordinates . Finding the distance from a point to a line is easy if the line is vertical or horizontal. We simply find the difference between the appropriate coordinates of the point and the line. In fact, for vertical lines, this is the only way to do it, since the other methods require the slope of the line, which is undefined for evrtical lines.

Method 2: (If you're looking for an equation) Distance = | Px - Lx |

Hope this helps!

Solve for x 6x^2=2x-1
leva [86]

Answer:

\displaystyle x=\frac{1\pm i\sqrt{5}}{6}

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Quadratic Formula: \displaystyle x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}

<u>Algebra II</u>

  • Imaginary Roots: √-1 = i

Step-by-step explanation:

<u>Step 1: Define</u>

6x² = 2x - 1

<u>Step 2: Rewrite</u>

  1. Subtract 2x on both sides:                    6x² - 2x = -1
  2. Add 1 to both sides:                               6x² - 2x + 1 = 0

<u>Step 3: Identify Variables</u>

a = 6

b = -2

c = 1

<u>Step 4: Solve for </u><em><u>x</u></em>

  1. Substitute [QF]:                       \displaystyle x=\frac{2\pm\sqrt{(-2)^2-4(6)(1)} }{2(6)}
  2. Exponents:                              \displaystyle x=\frac{2\pm\sqrt{4-4(6)(1)} }{2(6)}
  3. Multiplication:                         \displaystyle x=\frac{2\pm\sqrt{4-24} }{12}
  4. (Square Root) Subtract:         \displaystyle x=\frac{2\pm\sqrt{-20} }{12}
  5. Factor:                                    \displaystyle x=\frac{2\pm \sqrt{-1} \sqrt{20} }{12}
  6. Simplify:                                 \displaystyle x=\frac{2\pm 2i\sqrt{5} }{12}
  7. Factor GCF:                           \displaystyle x=\frac{2(1\pm i\sqrt{5} )}{12}
  8. Simplify:                                 \displaystyle x=\frac{1\pm i\sqrt{5}}{6}
