A quadratic equation is an equation where the highest power is 2. To solve a quadratic equation we must make it equal zero.
To factorise this quadratic you have to find 2 numbers that multiply together to make the end number (6) and add to make the middle number (5). These numbers would be 2 & 3. Therefore, the solution would be
To check this is correct you multiply out the brackets.
The formula for finding interior angles in REGULAR polygons is:
(number of sides - 2) x 180 =( (number of sides - 2) x 180) / number of sides
number of sides
The formula for finding exterior angles in REGULAR polygons is:
360 = 360/ number of sides
Number of sides
