12 (4x-2)-2/3 (6x+9)≤4 One solution was found : x ≥ -11/2 Rearrange: Rearrange the equation by subtracting what is to the right of the less equal sign from both sides of the (2x/2x+5)= (2/3) (-6/4x+10) Two solutions were found : x = (-3-√69)/6=-√ 69 = -1.884 x = (-3+√69)/6=-1/2+1/6√ 69 = 0.884 Rearrange: Rearrange the
Ejemplo: 2x+5 = 3x-1 La solución de la ecuación es x = 4 ya que 2 ·4+5 = 13 y 3 ·4+1 = 13 La solución de la ecuación no es x = 3 ya que 2 ·3+5 = 11 y 3 ·3+1 = 10 En una ecuación se pueden distinguir varios elementos: • Incógnita – Es la letra que aparece en la ecuación.

Circleon a Graph. Let us put a circle of radius 5 on a graph: Now let's work out exactly where all the points are.. We make a right-angled triangle: And then use Pythagoras:. x 2 + y 2 = 5 2. There are an infinite number of those points, here are some examples:

WHEN THE SUM of two numbers multiplies their difference --. ( a + b ) ( a − b) -- then the product is the difference of their squares: ( a + b ) ( a − b) = a2 − b2. For, the like terms will cancel. (Lesson 16.) Symmetrically, the difference of two squares can be factored: x2 − 25 = ( x + 5) ( x − 5) x2 is the square of x. 25 is the
