Example Questions
Example Question #41 : Solving Equations
Solve for .
Take the square root on both sides. Remember to account for a negative square root.
We will treat as two different equations.
Subtract
on both sides. When adding another negative number, we treat as a sum and add a minus sign in the end.
Subtract
on both sides. Since
is greater than
and is negative, our answer is negative. We treat as a subtraction problem.
Example Question #42 : Solving Equations
Solve for .
Let's subtract
on both sides. It will be easier to square both sides to get rid of the radical.
This is recognition of a quadratic equation.
We need to find two terms that multiply to the c term but add up to the b term.
Solve individually for zero.
Add
on both sides.
Add
on both sides.
We need to check our answers.
If , then
If , then
Clearly, doesn't work so our final answer is
.
Example Question #51 : Single Variable Algebra
Solve for .
This is a one step, one variable problem. This means we want to isolate x on one side of the equation with all other constants on the other side. To do this perform the opposite operation to manipulate the equation
Subtract on both sides. Since
is greater than
and is negative, our answer is negative.
We treat as a subtraction problem.
Example Question #52 : Single Variable Algebra
Solve for .
This is a two step, one variable problem. This means we want to isolate x on one side of the equation with all other constants on the other side. To do this perform the opposite operation to manipulate the equation
Subtract on both sides.
Multiply on both sides.
