Answer:
y = (x - 4)² - 25
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
y = (x + 1)(x - 9) ← expand factors using FOIL, thus
y = x² - 8x - 9
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
y = x² + 2(- 4)x + 16 - 16 - 9
= (x - 4)² - 25 ← in vertex form
-16+-x/4=-3
-x/4=13
-x=52
x=-52
Answer:
The answer to your question is x = 10/19
Step-by-step explanation:
Equation
6 / (x + 2) = 5 / 4x
To solve this equation use cross multiplication
6(4x) = 5(x + 2)
Simplify
24x = 5x + 10
Subtract 5x in both sides of the equation
24x - 5x = 5x - 5x + 10
Simplify
19x = 10
Divide by 19 both sides
19x/19 = 10/19
Simplify
x = 10/19
