Question 368447
Do you have to use the FOIL method? 
With more than 2 elements, the distributive property is easier.
{{{(x^2+2x-3)(x^2-5x+7)=(x^2)(x^2-5x+7)+(2x)(x^2-5x+7)+(-3)(x^2-5x+7)}}}
{{{(x^2+2x-3)(x^2-5x+7)=(x^4-5x^3+7x^2)+(2x^3-10x^2+14x)+(-3x^2+15x-21)}}}
{{{(x^2+2x-3)(x^2-5x+7)=highlight(x^4-3x^3-6x^2+29x-21))}}}
