Introduction: A quadratic equation is an equation of degree 2 that is in the form x squared plus bc plus c equals 0. If the equation can be factored, then we are able to find the r
Introduction: A linear equation in one variable is an equation of degree 1. Example 1: 2x – 3 equals 12. To solve a linear equation means to find the x-intercept of the line
A key element in teaching mathematics is to make students actually WANT to be there. This means not only answering the age-old question “When am i gonna use this stuff?”
Example 1: Simplify. x – 3x -y -11y -4x – 3 Solution 1: (x-3x-4x) plus (-y-11y) equals -6x -12y. Example 2: simplify. 5(a-3b)-6(2a-3b) Solution 2: 5a-15b-12a plus 18b)
Polynomials are algebraic expressions of three main types. Monomials, binomials, and trinomials. One termed expressions are referred to as monomials. Ex 3xy two termed expressions
When we factor a polynomial we are taking a sum or difference of terms and writing them as a product of factors.Example . Ax – Ay equals A(x-y). The factors are A and x-y. Th
Ex. 1 Mary ate 3 slices of her 8 slice pizza. Write the slices of pizza that Mary ate as a fraction. Soln. 3/8. Ex2. Jim and Peter did 3/5 work and 2/3 work on building a boat. Wor
Ex 1. Mary had 6 dogs and Peter had 8 dogs. How many dogs did they have in total? Soln: 6 plus 8 equals 14. Ex. 2 John had 12 kittens. Bill had 3 less kittens. How many kittens did
Ordering a set of numbers means arranging them from smallest to largest. For example, to order the set of whole numbers, W=0,1,2,3,4,…, you simply list them in ascending order as
The best learning takes place when the students pair up and work in groups of two. Students can then take their work from one another or teach one another so they can learn from ea
To visualize and classify real numbers, we can graph them on a number line and identify their types. For example, consider the following: In Example 1, let’s graph: In Example 2,
When multiplying and dividing negative numbers, remember that multiplying two negative numbers gives a positive result, while multiplying a negative and a positive number results i
