How to Subtract Two Equations
What is the process of subtracting two equations?
Given the following data:
- Equation 1 = 7x - 9
- Equation 2 = 2x^2 - 11
Answer:
To subtract two equations, in this case equation 1 from equation 2, follow these steps:
Calculate the subtraction as shown below:
In this exercise, you're required to subtract equation one (7x - 9) from equation two (2x^2 - 11). This means you will subtract one equation from the other to produce a new equation.
Mathematically, the expression is as follows:
2x^2 - 11 - (7x - 9)
Opening the bracket, you get:
2x^2 - 11 - 7x + 9
2x^2 - 7x - 11 + 9
2x^2 - 7x - 2
Note: The resulting equation is a quadratic equation.
