802h2−16−0
Solution
802h2−16
Show Solution

Factor the expression
2(401h2−8)
Evaluate
h2×802−16−0
Use the commutative property to reorder the terms
802h2−16−0
Removing 0 doesn't change the value,so remove it from the expression
802h2−16
Solution
2(401h2−8)

Find the roots
h1=−4012802,h2=4012802
Alternative Form
h1≈−0.141245,h2≈0.141245
Evaluate
h2×802−16−0
To find the roots of the expression,set the expression equal to 0
h2×802−16−0=0
Use the commutative property to reorder the terms
802h2−16−0=0
Removing 0 doesn't change the value,so remove it from the expression
802h2−16=0
Move the constant to the right-hand side and change its sign
802h2=0+16
Removing 0 doesn't change the value,so remove it from the expression
802h2=16
Divide both sides
802802h2=80216
Divide the numbers
h2=80216
Cancel out the common factor 2
h2=4018
Take the root of both sides of the equation and remember to use both positive and negative roots
h=±4018
