h2−837
Show Solution
Find the roots
h1=−393,h2=393
Alternative Form
h1≈−28.930952,h2≈28.930952
Evaluate
h2×1−837−0
To find the roots of the expression,set the expression equal to 0
h2×1−837−0=0
Any expression multiplied by 1 remains the same
h2−837−0=0
Removing 0 doesn't change the value,so remove it from the expression
h2−837=0
Move the constant to the right-hand side and change its sign
h2=0+837
Removing 0 doesn't change the value,so remove it from the expression
h2=837
Take the root of both sides of the equation and remember to use both positive and negative roots
h=±837
