Question
x2−(a−3)x×9=0
Solve the equation
Solve for x
Solve for a
x=0x=9a−27
Evaluate
x2−(a−3)x×9=0
Multiply the terms
More Steps
Evaluate
(a−3)x×9
Use the commutative property to reorder the terms
(a−3)×9x
Multiply the terms
9x(a−3)
x2−9x(a−3)=0
Rewrite the expression
x2+(−9a+27)x=0
Expand the expression
x2−9ax+27x=0
Factor the expression
More Steps
Evaluate
x2−9ax+27x
Rewrite the expression
x×x−x×9a+x×27
Factor out x from the expression
x(x−9a+27)
x(x−9a+27)=0
When the product of factors equals 0,at least one factor is 0
x=0x−9a+27=0
Solution
More Steps
Evaluate
x−9a+27=0
Move the expression to the right-hand side and change its sign
x=0−(−9a+27)
Subtract the terms
More Steps
Evaluate
0−(−9a+27)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
0+9a−27
Removing 0 doesn't change the value,so remove it from the expression
9a−27
x=9a−27
x=0x=9a−27
