I know of two ways to solve quadratic equations. The first is through factoring. Let us take the example (x^2)+2x+1=0. We can factor this equation out and the factors would be (x+1)(x+1)=0. To solve for the roots, we equate each factor to 0, that is
x+1=0; x+1=0
In this case, the factors are the same so the root of the equation is
x=1.
The other way is to use the quadratic formula. The quadratic formula is given as [-b(+-)sqrt(b^2-4ac)]/2a where, using our sample equation above, a=1, b=2 and c=1. Substitute these to the formula, and you will get the same answer as the method above.
It would be exactly 1.2778 yards.
Solution:
we are given that
Don walked 3 3/5 miles on Friday
It can be re-written as
miles
3 5/8 miles on sunday.
It can be re-written as
miles
an d He walk 3.7 miles on satarday.
The distances from least to greatest is 3.6, 3.625, 3.7
or
The distances from least to greatest is 
miles, 
miles, 3.7 miles.
X=5.
Explanation:
Take 3x+1=5x-9 and subtract 1 from both sides.
Now you have 3x=5x-10, Subtract 5x from both sides to get -2x= -10
Now divide both sides by -2 and you have x=5 :).
Answer:
± 5
Step-by-step explanation:
2x/-5 = -10/x
2x^2 = 50
x^2 = 25
x = ± 5
