The method of factorization is used to find the roots of a given polynomial. Roots are the solutions of the function. Graphically, these roots are where the curve passes the x-axis. The first step to do is to find the common factor of the equation. That would be x. So you place it outside of the parenthesis.
x³-4x²+45x = x(x² - 4x + 45)
If you solve the quadratic equation inside the parenthesis using the quadratic formula, the roots are imaginary. Therefore, the quadratic equation is already a prime polynomial.
The final answer is x(x² - 4x + 45).
Divide the total price by the total number of books from each printer to find the price per book:
Printer A: $350 / 100 books = $3.50 per book
Printer B: $150 / 40 books = $3.75
Printer A has the lowest price.
Answer:
1. The like terms are 11x and 2x and the terms are 11x and 2x
2. The like terms are 9x and -5x and the terms are 9x and -5x
3. the like terms are (21x and x) and (6 and -5) and the terms are 21x, 6, -x, and -5.
4. The like terms are (8x and -3x) and (14 and 1). And the terms are 8x, 14, -3x, and 1.
