Simplify the expression
h2−135
Evaluate
h2×1−135−0
Any expression multiplied by 1 remains the same
h2−135−0
Solution
h2−135
Show Solution
Find the roots
h1=−315,h2=315
Alternative Form
h1≈−11.61895,h2≈11.61895
Evaluate
h2×1−135−0
To find the roots of the expression,set the expression equal to 0
h2×1−135−0=0
Any expression multiplied by 1 remains the same
h2−135−0=0
Removing 0 doesn't change the value,so remove it from the expression
h2−135=0
Move the constant to the right-hand side and change its sign
h2=0+135
Removing 0 doesn't change the value,so remove it from the expression
h2=135
Take the root of both sides of the equation and remember to use both positive and negative roots
h=±135
