X^2-5x+6=0 quadratic form

x = 3,2

Step-by-step explanation:

solve for x by finding a,b,c and then apply the quadratic formula.

x

=

−

3

x

=

−

2

Explanation:

The quadratic formula is:

⇒

x

=

−

b

±

√

for a quadratic of the form

a

x

+

b

x

+

.

We have

a

=

,

b

=

, and

c

=

.

Hence,

I'm not sure why you wanted to use the quadratic formula, but you could just factor the quadratic:

x

2

+

5

x

+

6

=

(

x

+

)

(

x

+

2

)

=

0

x

+

3

=

→

x

=

−

3

and

x

+

2

=

0

→

x

=

−

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
