Question
Solve the equation
h1=−39,h2=0
Alternative Form
h1≈−2.080084,h2=0
Evaluate
−h4=1×h×9
Multiply the terms
More Steps
Evaluate
1×h×9
Rewrite the expression
h×9
Use the commutative property to reorder the terms
9h
−h4=9h
Add or subtract both sides
−h4−9h=0
Factor the expression
−h(h3+9)=0
Divide both sides
h(h3+9)=0
Separate the equation into 2 possible cases
h=0h3+9=0
Solve the equation
More Steps
Evaluate
h3+9=0
Move the constant to the right-hand side and change its sign
h3=0−9
Removing 0 doesn't change the value,so remove it from the expression
h3=−9
Take the 3-th root on both sides of the equation
3h3=3−9
Calculate
h=3−9
An odd root of a negative radicand is always a negative
h=−39
h=0h=−39
Solution
