What is the solution (not answer) to (not too) x^2 - 3x + 5 = 0?
This is a quadratic equation. Two possible approches to solving it are
1) quadratic formula, and
2) completing the square.
Let's use the quadratic formula:
a=1, b= -3, c = 5
Then
-(-3) plus or minus sqrt( [-3]^2 - 4(1)(5) )
x = --------------------------------------------------------
2
3 plus or minus sqrt(9-20) 3 plus or minus i*sqrt(11)
= ------------------------------------- = ------------------------------------
2
Please note: These are complex roots, due to the " i ".
Draw the number line then put the numbers on the number line by twos. Fore example, 2-4-6-8-10
4 tennis balls/package
4 is the GCF of the two numbers. Any numbers higher than these either go into one or neither numbers of tennis balls. The numbers below aren't the greatest number or else don't go into one or neither numbers. Hope this helps!
