WebPascal's Triangle is probably the easiest way to expand binomials. It's much simpler to use than the Binomial Theorem, which provides a formula for expanding binomials. The formula for Pascal's Triangle comes from a relationship that you yourself might be able to see in the coefficients below. (x + y) 0 (x + y) 1 (x + y)² (x + y) 3 (x + y) 4 1 WebStep 1 – Multiply out the first two brackets (use FOIL) Step 2 – Multiply the result x^2 +3x+2 by (3x+3) This requires \bf {6} separate multiplications, shown below. Finally we must collect the like terms \textcolor {red} {3x^3+3x^2}\textcolor {blue} {+9x^2+9x}\textcolor {limegreen} {+6x+6} = 3x^3 + 12x^2 +15x + 6 Level 6-7 GCSE iphone screen mirroring just spinning
4 Ways to Solve a Cubic Equation - wikiHow
WebA cubic equation has the form ax3 +bx2 +cx+d = 0 It must have the term in x3 or it would not be cubic (and so a 6= 0 ), but any or all of b, c and d can be zero. For instance, x 3−6x2 +11x− 6 = 0, 4x +57 = 0, x3 +9x = 0 are all cubic equations. Just as a quadratic equation may have two real roots, so a cubic equation has possibly three.
