so.. whatever "x" and "y" amounts are, we know that, added together, they must yield 14lbs
thus x + y = 14
and whatever the cost of each is, 7x + 4y must be 14*5
7x+4y = 70
thus
solve for "x", to see how much of the $7/lb type will be needed
what about the $4/lb one? well, y = 14 - x
The two roots 
and 
are called <u>conjugate</u> radicals
<h3>Conjugate of a radical </h3>
The conjugate of a radical is the value which when multiplied with the radical expression clears the radical. Conjugates have the same numbers but the opposite sign in the middle.
The given roots are
