B. Multiply
(r + d) (r^2 - rd + d^2)
1. Multiply
(-3n)^2(2n^7)^2
E. Find the solutions. What is/are the solutions of,
a^2 + 5a - 14 = 0
F. Subtract the polynomials

x - 6 x + 6 x^2 - 36
(4a^4 - 2a^3 +2a^2 + 13a - 8)+(a^5 + 8a^3 + 8a^2 - 2a + 6)+(-7a^4 + a^2 - 9a -9)
(2x^2 - 8xy + y^2) + (-5x^2 - 5xy - y^2) + (x^2 + xy - 4y^2)
I. find the x-intercepts for the graph of the equation y = x^2 + 2x - 3
J. Solve for x
4x(x - 8) - 5x (x - 7) = -4
K. Find the trinomial
