Equation: -5x2 + 600x + 100 = 0
Note: In this problem, 1/2 represents the square root, not the 0.5 fraction.
- To make life easy, factor and divide 5 out from both sides.
5 ( -x2 + 120x + 20 ) = 0/5
-x2 + 120x + 20 = 0
- There are different ways to solve a quadratic equation. In this case, the simplest way is by the quadratic formula: x = [ -b ± ( b2 - 4ac)1/2] / 2a
Since, a = -1, b = 120, and c = 20,
x = { -120 ± [ (-120)2 - 4(-1)20]1/2} / 2(-1)
- Now, solve for x.
x = [ -120 ± ( 14400 + 80 )1/2] / -2
x = [ -120 ± ( 14480)1/2] / -2
- The square root of 14480 is an irrational number, so you pretty much have your answer, unless if your teacher wants you to write it in a certain way. If your teacher doesn't tell you, you might want to ask.
x = ( 120 ± 144801/2 ) / 2
x = ( 60 ± 1/2(14480)1/2 )

What is the value of 6 squared plus 8 squared?
102 or 100
What is 6 squared plus 8 squared?
To calculate 6 squared plus 8 squared, you first need to square each number individually. 6 squared is 6 x 6, which equals 36. 8 squared is 8 x 8, which equals 64. Adding these two results together, you get 36 + 64, which equals 100. So, 6 squared plus 8 squared is 100.
