Formula : (x+a)(x+b)(x+c) = x^{3}+x^{2}(a+b+c)+x(ab+bc+ca)+abcExample: Find the product of (1+a)(1+b)(1+c). Solution: Using above formula, Here a=a, b=b, c=c and x=1 (x+a)(x+b)(x+c) = (1+a)(1+b)(1+c) = 1^{3}+1^{2}(a+b+c)+1(ab+bc+ca)+abc = 1+a+b+c+ab+bc+ac+abc Directions: Solve the following problems. Also write at least ten examples of your own.
