Question

write factorization formulas and pythagoras tricks.

Answer 1

Your factorised formula is always of the form: y = …(… + …) or y = …(… – …). In both terms of formula y = 6 x 2 + 15 x is a factor 3 x . Because you can write the formula as y = 2 × 3 × x × x + 3 × 5 × x . In all terms of formula y = 8 x 2 + 4 x – 20 is a factor 4.



The other two sides that are adjacent to the right angle are called legs of the triangle. The theorem, also known as the Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.
