While simultaneous equation with two equations and two unknowns should be easy enough to solve using elimination, substitution, or graph sketching, simultaneous equations with more than two equations and two...

First off, write your equation in the form: ax^ 2 +by+c=0 with a, b and c being your constant coefficients. First, we will factorise out a such that: a(x^ 2 +(b/a)x)+c Now divide b by 2. Then write a(x+(b/2a...

There are different ways of factoring an equation depending on the type. A few are highlighted here: 1) Taking out a common factor General formula : ab + ac = a ( b+ c) Step 1: realise that all terms of the ...

for this type of question, integral by parts should be used . This involves using the formula for intregation by parts: lets first break apart the x and e 10x into two parts - "u" and "v"...

Step 1: Add a cumulative frequency column to the table Step2: Use the formula n/2 (where n is the final total in the cumulative frequency column) to find the class the median, Q 2 , is in. Let n/2= a, so tha...
