Math Problem Statement
- (a/2a^2-7a+3) + (1/a^2+a - 12) = (a+1/2a^2+7a-4)
Solution
Let's break down and solve the given equation step by step:
The equation is:
Step 1: Simplify the terms.
First, we note that the equation consists of rational expressions, so we will look for a common denominator to combine the left-hand side.
- The denominators on the left side are and .
- The denominator on the right side is .
Let's attempt to factor these expressions.
Factor the denominators:
-
:
We need two numbers that multiply to and add up to . These are and .
So we can factor the quadratic as: -
:
We need two numbers that multiply to and add up to . These are and .
So we can factor the quadratic as: -
:
We need two numbers that multiply to and add up to . These are and .
So we can factor the quadratic as:
Step 2: Substitute the factored forms.
The equation becomes:
Step 3: Combine the terms on the left side.
We need a common denominator to combine the fractions on the left. The common denominator is . We rewrite each term accordingly:
Thus, the equation now becomes:
Step 4: Simplify the numerator on the left-hand side.
Expand and combine like terms: Thus, the numerator on the left-hand side is:
Now, the equation is:
Step 5: Eliminate the common terms.
We can cancel out the common factors and from both sides of the equation. This simplifies to:
Step 6: Solve the simplified equation.
Multiply both sides by to eliminate the denominator:
Expand the right-hand side:
Step 7: Simplify and solve for .
Cancel the terms from both sides: Add to both sides: Add 1 to both sides: Finally, divide by 8:
Conclusion:
The solution to the equation is .
