Question
x2 -14x + 40 = 2x + 1
What is the sum of the solutions to the given equation?
- -16
- -14
- 14
- 16
The correct answer is: 16
x2 - 14x + 40 = 2x + 1
x2 - 16x + 39 = 0
In Quadratic equation ax2 + bx + c = 0, the sum of solutions = 
Here a = 1, b = -16 and c = 39
The sum of solutions

Interior angles are the angles contained within a shape or the region enclosed by two parallel lines transversely intersected.
¶Interior angles form in two ways in geometry. The first occurs within a polygon, and the second occurs when a transversal cuts parallel lines. Angles are classified into various types based on their measurements. Other angles are known as pair angles because they appear in pairs to exhibit a specific property. Interior angles are one example.
¶Sum, S = (n − 2) × 180°

Use polynomial identities to factor the polynomials or simplify the expressions : 
Polynomial identities are equations that are true for all possible values of the variable. We can perform polynomial multiplication by applying the distributive property to the multiplication of polynomials.
