Question
Solve the equation
a=0
Evaluate
9a=(a5×6)(−5)
Remove the parentheses
9a=a5×6(−5)
Multiply
More Steps

Evaluate
a5×6(−5)
Rewrite the expression
−a5×6×5
Multiply the terms
−a5×30
Use the commutative property to reorder the terms
−30a5
9a=−30a5
Add or subtract both sides
9a−(−30a5)=0
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
9a+30a5=0
Factor the expression
3a(3+10a4)=0
Divide both sides
a(3+10a4)=0
Separate the equation into 2 possible cases
a=03+10a4=0
Solve the equation
More Steps

Evaluate
3+10a4=0
Move the constant to the right-hand side and change its sign
10a4=0−3
Removing 0 doesn't change the value,so remove it from the expression
10a4=−3
Since the left-hand side is always positive or 0,and the right-hand side is always negative,the statement is false for any value of a
a∈/R
a=0a∈/R
Solution
a=0
