Answer:

\frac{3x}{x + 2}  +  \frac{4x}{x - 2}  \\  \frac{(3x(x - 2) + (4x(x + 2))}{(x + 2)(x - 2)}

(3x²-6x+4x²+8x)/(x²-2²)

(7x²+2x)/(x²-4)

comparing with

ax²+bx/x²+c

we get

a=7

b=2

c=-4

Write a quadratic equation in STANDARD FORM given the roots:<br> 1, 1/2
Zigmanuir [339]

Answer:

f(x) = 2x^2 - 3x + 1

Step-by-step explanation:

The root 1 is associated with the factor (x - 1).

The root 1/2 is associated with the factor (x - 1/2), which in turn is equivalent to (2x -1)

The quadratic in question is f(x) = (x - 1)(2x - 1).  To write this in standard form, perform the indicated multiplication:

f(x) = 2x^2 - 2x - x + 1, or f(x) = 2x^2 - 3x + 1

PLEASE HELP I WILL MARK BRAINLIST TO WHOEVER ANSWERS FIRST !!
dezoksy [38]

Answer:

Graph (6, 5) and (-6, -3), and then use a ruler (optional), and draw a line between them, and a little after the points.

Step-by-step explanation:

y = 2/3x + 1

Substitute different numbers for x, and find y:

You don't really want to work with fractions, so try to find a number that when multiplied by 2/3, gives you a whole number

x = 6

y = 2/3(6) + 1

y = 12/3 + 1

y = 4 + 1

y = 5

Point: (6, 5)

x = -6

y = 2/3(-6) + 1

y = -12/3 + 1

y = -4 + 1

y = -3

Point: (-6, -3)

Graph these two points, and then use a ruler (optional), and draw a line between them, and a little after the points.
