Use the x-intercept method to find all real solutions of the equation. x^3- 6x^2 + 3x + 10 = 0
a. X= 1, -2, or - 5
b. X=-1, 2, or - 5
c. X= 1, - 2, or 5
d. X=-1, 2, or 5

Add, subtract, multiply, or divide as indicated. list any restrictions for the variable(s) and simplify the answers when possible. 1) x-2 / x+5 + 3x / 2x-1 2) x+6 / x-6 - x^2 / x+6 3) x+9 / x-4 + x+2 / x^2-11x+28 4) x / x^2-64 + 11 / 2x^2+11x-40 5) 5 / x + 11 / x-3 - x-4 / x^2+2x-15
