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

To compare the fractions we need to find a common denomanator.
This means we need to find a common number (to the denomanator) in each number set of times tables.
In this case we can use 6 as a common denomator.

One of out fractions is already out of 6 so we just need to convert the other one.
We can just double 4/3 to give us 8/6.

We can now compare the data, we have 8/6 and 8/6.
These fractions show that both John and Mya use the same amount of milk for their recipies, this being 8/6 or 1 1/3 as a mixed number.
