Linear Systems: Linear And Quadratic Systems Worksheet

Linear systems consist of equations with variables that have a degree of 1. In other words, the variables are not squared or raised to any power other than 1. Linear systems can be represented in the form Ax + By = C, where A, B, and C are constants and x and y are variables.

Examples of Linear Systems

• 2x + 3y = 5
• x – y = 2
• -3x + 2y = 1

Solution Methods for Linear Systems

System of Equations	Solution Method	Solution
2x + 3y = 5x y = 2	Substitution	x = 1, y = 1
x y = 2-3x + 2y = 1	Elimination	x = 3, y = 1

Quadratic Systems

Quadratic systems consist of equations with variables that have a degree of 2. In other words, at least one of the variables is squared. Quadratic systems can be represented in the form ax² + bx + c = 0, where a, b, and c are constants and x is a variable.

Methods for Solving Quadratic Systems, Linear and quadratic systems worksheet

Method	Steps
Factoring	Factor the quadratic equation into two binomials. Set each binomial equal to zero and solve for the variable.
Completing the Square	Add and subtract the square of half the coefficient of the x-term. Factor the resulting expression as a perfect square trinomial. Solve for the variable.
Quadratic Formula	Use the quadratic formula: x = (-b ± √(b²- 4ac)) / 2a.

Systems of Linear and Quadratic Equations

Systems of linear and quadratic equations consist of one linear equation and one quadratic equation. These systems can be solved by substitution or elimination.

Steps for Solving Systems of Linear and Quadratic Equations

• Solve the linear equation for one of the variables.
• Substitute the expression for the variable from the linear equation into the quadratic equation.
• Solve the resulting quadratic equation for the other variable.
• Substitute the value of the variable from the quadratic equation back into the linear equation to find the value of the first variable.

Applications of Linear and Quadratic Systems

Linear and quadratic systems have many real-world applications, including:

Application	Corresponding System of Equations	Solution
Projectile Motion	v = u + ats = ut + 1/2at²	v = final velocity u = initial velocity a = acceleration t = time s = distance
Finance	I = PrtA = P(1 + r/n)^(nt)	I = interest P = principal r = interest rate t = time n = number of compounding periods per year A = future value

Practice Problems

Problem	Solution Method	Solution
Solve the system of equations:2x + 3y = 5x y = 2	Substitution	x = 1, y = 1
Solve the quadratic equation:x² 5x + 6 = 0	Factoring	x = 2, x = 3
Solve the system of equations:y = x + 1 x² + y² = 25	Substitution	x = 2, y = 3x = 2, y = 1
