Write the quadratic equation that has roots (√3+1)/2 and (√3 -1 )/2, if its coefficient with x^2 is equal to:

a) 1
b) 5
c) - 1/2
d) √3

The equation is:

(A)

(B)

(C)

d) √3

Step-by-step explanation:

If the roots of the quadratic equation are:

This means:

x= OR

x-=0 or x-

If a=0 or b=0, then ab=0

Therefore:

Therefore the coefficient of  here is 1.

b) To make 5 the coefficient of

Simply multiply by 5

This gives:

c)

To make the coefficient of

Simply multiply by

This gives:

d) √3

To make   the coefficient of

Simply multiply by

This gives:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
