Answer:
1 ± √47
Step-by-step explanation:
Combine like terms in 2x^2 +3 x-7 =x^2 +5x +39:
2x^2 - x^2 = x^2 (first term);
3x - 5x = -2x (second term);
-7 - 39 = -46 (third term)
Then we have, all on the left side, x^2 - 2x - 46, which is a quadratic equation. Here the coefficients are a = 1, b = -2 and c = -46.
Then the discriminant, b^2 - 4ac, is:
(-2)^2 - 4(1)(-46) = 4 + 184.
The roots are:
-(-2) ±√188 2 ± √4√47

<u><em>The complete question is</em></u>
James has to buy juice for his class party. there are several brands of juice at the store, and each container is a different size and price. write a formula that will help James find the price per milliliter for each brand.
x=price of juice
y=number of milliliters in carton
z=price per milliliter
we know that
The price per milliliter for each brand, is the same that the unit rate
so
To find out the unit rate , divide the price of juice by the number of milliliters in carton
so
