I was tutoring my brother for calculus 2 the other day on the trapezoidal rule for area approximation, the following function:√(x2+1) when I noticed he was making a consistent horrible mistake... He kept pulling out the +1 out of the square root to try to simplify this. So he claimed, √(1 +1)= √1+√1= 1+1 = 2. An obvious problem with this is the claim... read more

When in doubt you can always use the Quadratic Formula: X = (-b ±√(b2-4ac))/2a to solve or find the roots of any Quadratic Equation. A quadratic equation is an equation that looks like: 0 = aX2+bX+c. In your case with 4X2+6X-2 = -7 we just have to add seven...

When I was studying to be a teacher, one of the classes I had to take was Literacy in Secondary Education. Since the word literacy is associated to reading and writing by most, it would strike many as a surprise that Math teachers have to take courses on literacy. However, literacy is the most practical and crucial aspect of ANY academic discipline, simply because it involves the ability... read more

Key here is to distinguish between the general equation of a line, the point slope formula, and the slope intercept equation of the line. Since you are looking to find the slope-intercept equation of a line, I will cover that first. The slope intercept form is: y = mx +...

The first thing is to do is find the Least Common Denominator (LCD) of the three fractions. We find the LCD by finding the Least Common Multiple(LCM) of the Denominators, 3, 4, and 24. The LCM is the smallest multiple other than 0 that a set of numbers share in common. To find...
