Two equations are equivalent if they have exactly the same solutions. For example, 2x-1 = x+3 and x+1=5 are equivalent since x=4 is the solution for each equation. We need some procedures that will allow us in a step-by-step manner to find the solutions to equation...
Observe that (x-4) and (4-x) are opposite in sign. = (x-4) (2 x-3)− 1 (− 4+x) (4+x) Factor − 1 out of (+ 4-x) to obtain − 1 (− 4+x) = 2 x-3− 1 (4+x) Apply the basic rule of fractions, since (x-4) and (− 4+x) are equivalent. =...
I know that most you who read my blog teach mathematics at either the high school or college level. I'd like to ask you a question (at the end of the post). It is about how our schools teach students to show that two mathematical quantities are equal. Th

It should be noted that there are more than just four factors in the expression 5xyz. The obvious factors are 5, x, y, and z. But 5x is also a factor. Other factors are 5xy, xy, 5yz, xz, 5z, and so on. An exponent is sometimes referred to as a "power." For example, 53...
