Just wanted to ask where can I find the answer/step-by-step analysis of the multiple parentheses example on p. 83 of Math Essentials review book? The book specifically says to visit Veritas Prep on Demand for detailed, step-by-step analysis of this example.

Anyone knows the answer?

Thanks,
Pia

(x^3)(1 + 3(x + 2 - (y^2)(xy - 3x^2)) - y)

(x^3)(1 + 3(x + 2 - x(y^3) - 3(x^2)(y^2) - y)

(x^3)(1 + 3x + 6 - 3x(y^3) - 9(x^2)(y^2) - 3y)

x^3 + 3x^4 + 6x^3 - 3(x^4)(y^3) - 9(x^5)(y^2) - 3y(x^3)
