Understanding the Problem

The given problem involves finding the missing polynomial in an equation. The equation is presented as: ${ ? - \left(20 - 4x - 5x^2\right) = 20 - 7x^2 }$ . To solve this problem, we need to isolate the missing polynomial by simplifying the equation.

Simplifying the Equation

To simplify the equation, we need to start by removing the parentheses on the left-hand side of the equation. This can be done by distributing the negative sign to the terms inside the parentheses: ${ ? - 20 + 4x + 5x^2 = 20 - 7x^2 }$ .

Combining Like Terms

Next, we need to combine like terms on both sides of the equation. On the left-hand side, we can combine the constant terms and the x terms: ${ ? - 20 + 4x + 5x^2 = 20 - 7x^2 }$ . On the right-hand side, we can combine the constant terms and the x^2 terms: ${ ? - 20 + 4x + 5x^2 = -20 + 7x^2 }$ .

Isolating the Missing Polynomial

Now, we need to isolate the missing polynomial by moving all the terms to the left-hand side of the equation. We can do this by adding 20 to both sides of the equation: ${ ? + 4x + 5x^2 = 7x^2 }$ .

Simplifying the Equation Further

Next, we need to simplify the equation further by moving all the terms to the left-hand side of the equation. We can do this by subtracting 7x^2 from both sides of the equation: ${ ? + 4x + 5x^2 - 7x^2 = 0 }$ .

Combining Like Terms Again

Now, we need to combine like terms again on the left-hand side of the equation. We can combine the x^2 terms: ${ ? + 4x - 2x^2 = 0 }$ .

Finding the Missing Polynomial

Finally, we need to find the missing polynomial by isolating the variable. We can do this by subtracting 4x from both sides of the equation: ${ ? - 2x^2 = -4x }$ .

Adding 2x^2 to Both Sides

Next, we need to add 2x^2 to both sides of the equation to isolate the variable: ${ ? = -4x + 2x^2 }$ .

Factoring Out the Common Term

Now, we need to factor out the common term from the right-hand side of the equation: ${ ? = 2x(x - 2) }$ .

Finding the Missing Polynomial

Finally, we need to find the missing polynomial by multiplying the common term by the variable: ${ ? = 2x(x - 2) }$ .

Conclusion

In conclusion, the missing polynomial is ${ 2x(x - 2) }$ . This can be simplified to ${ 2x^2 - 4x }$ .
