Answer:

(-8,13)

Step-by-step explanation:

I just graphed the coordinates that you were given and followed the line. Then checked my work with m a t h w a y . c o m

I checked that the slope of the two coordinates you were given were the same as the endpoint they gave you and the one i found and they were!

Good luck! You got this!

If you want my to explain a little more of how i found the answer just let me know!

2x2 - 12x + 10<br>what are the roots

Tcecarenko [31]

Answer:

5 & 1

Step-by-step explanation:

We can use the quadratic formula to solve this:

Quadratic Formula = $\frac{-b+-\sqrt{b^2-4ac} }{2a}$

So we will have 2 answers (roots).

a is the coefficient of x^2 (2)

b is the coefficient of x (-12)

c is the constant (10)

Now, substituting, we get:

x = $\frac{-b+-\sqrt{b^2-4ac} }{2a}=\frac{12+-\sqrt{(-12)^2-4(2)(10)} }{2(2)}=\frac{12+-\sqrt{64} }{4}=\frac{12+-8}{4}=\frac{12+-8}{4}=5,1$

Hence the roots are 5 & 1
