Determine the type and number of solutions of 4x^2-5x+1=0.
Arlecino [84]
<span>4x² - 5x + 1 = 0
a = 4; b = - 5, c = 1
</span>Δ = b² - 4.a.c
Δ = (-5)² - 4.4.1
Δ = 25 - 16
Δ = 9
<span>
x = - b </span>± √Δ / 2.a
x =  \frac{-5\± \sqrt{9} }{2*4}
x =  \frac{-5\±3}{8}
x' =  \frac{-5-3}{8} =  \frac{-8}{8} = -1
x' = \frac{-5+3}{8} = \frac{-2}{8} (\div2) = \frac{-1}{4}


A. Two real solutions (x' = -1 and x'' = -1/4)

We have given that a container of the coffee is \frac{1}{6} full

And it contains \frac{2}{3} of a pound so \frac{2}{3} pound

It means \frac{1}{6} f of container contain  \frac{2}{3}  pound coffee

So capacity of the container is \frac{\frac{2}{3}}{\frac{1}{6}}=4pound
