Answer:

x = -5, 1

Step-by-step explanation:

To factor an equation, break the polynomial into two binomials which multiply to make it. Find two numbers that multiply to C and add to B from ax^2 + bx + c.

-1 and 5 multiply to -5 and add to 4.

x^2+4x-5 = (x+5)(x-1)

The zeros are the factors set equal to 0 and solved.

(x+5) = 0

x=-5

(x-1) = 0

x=1

Mike drank more than half the juice in his glass. what fraction of the juice could Mike have drunk?
maxonik [38]
He drank more than half of his drink... So we need to look for fractions greater than 1/2.

First, lets find equivalents of 1/2

\frac{1}{2}= \frac{2}{4} = \frac{3}{6}= \frac{4}{8}

If all of these fractions are equal to 1/2, then by adding to the numerator of these fractions, we'l have fractions greater than 1/2.

 2 +1 3
__= ___
 4      4

3/4 is greater than 1/2

Mike could have drunken 3/4 of the juice

4/6>1/2 Mike could have drunken 4/6 of the juice

5/8 is greater then 1/2 Mike could have drank 5/8 of the drink.

Answer=3/4, 4/6, 5/8 and many more possible fractions
