Simplify the expression
h2−120
Evaluate
h2×1−120−0
Any expression multiplied by 1 remains the same
h2−120−0
Solution
h2−120
Show Solution
Find the roots
h1=−230,h2=230
Alternative Form
h1≈−10.954451,h2≈10.954451
Evaluate
h2×1−120−0
To find the roots of the expression,set the expression equal to 0
h2×1−120−0=0
Any expression multiplied by 1 remains the same
h2−120−0=0
Removing 0 doesn't change the value,so remove it from the expression
h2−120=0
Move the constant to the right-hand side and change its sign
h2=0+120
Removing 0 doesn't change the value,so remove it from the expression
h2=120
Take the root of both sides of the equation and remember to use both positive and negative roots
h=±120
