Question
Solve the equation
Solve for x
Solve for a
x=−a−3x=a−2
Evaluate
x2+5x−(a2+a−6)=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
x2+5x−a2−a+6=0
Factor the expression
More Steps
Evaluate
x2+5x−a2−a+6
Calculate
x2−ax+2x+ax−a2+2a+3x−3a+6
Rewrite the expression
x×x−xa+x×2+ax−a×a+a×2+3x−3a+3×2
Factor out x from the expression
x(x−a+2)+ax−a×a+a×2+3x−3a+3×2
Factor out a from the expression
x(x−a+2)+a(x−a+2)+3x−3a+3×2
Factor out 3 from the expression
x(x−a+2)+a(x−a+2)+3(x−a+2)
Factor out x−a+2 from the expression
(x+a+3)(x−a+2)
(x+a+3)(x−a+2)=0
When the product of factors equals 0,at least one factor is 0
x+a+3=0x−a+2=0
Solve the equation for x
More Steps
Evaluate
x+a+3=0
Move the expression to the right-hand side and change its sign
x=0−(a+3)
Subtract the terms
More Steps
Evaluate
0−(a+3)
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−a−3
Removing 0 doesn't change the value,so remove it from the expression
−a−3
x=−a−3
x=−a−3x−a+2=0
Solution
More Steps
Evaluate
x−a+2=0
Move the expression to the right-hand side and change its sign
x=0−(−a+2)
Subtract the terms
More Steps
Evaluate
0−(−a+2)
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+a−2
Removing 0 doesn't change the value,so remove it from the expression
a−2
x=a−2
x=−a−3x=a−2
