    Write the equation in standard form for the line that passes through (6, -1) and (10,-*) So far I have -8-1 is -9 and 10-6 is 4, is the -9 correct? Then y plus 10 equals 9/4(x - 8) Then multiply by 2 so 2y plus 20 equals 18/4x - 146/4 Is this correct so

    4. Solve the equation using all three methods below. Factoring, completing the square, quadratic formula. x^2 + 3x - 4 = 0 and 4x^2 = 9 it seems like x^2 + 3x - 4 = 0 equals x = 1, -4 from all three methods but Im not sure 4x^2 = 9 equals x = 3/2, -(3/2)

    What does 3x^3-3x+2=0 come out to? How would I solve this? Is the x cubed supposed to be x squared? You can compare the equation with the identity: (a+b)^3 = a^3 + 3 a^2 b + 3 a b^2 + b^3 which you can rewrite as: (a + b)^3 = 3 ab (a + b) + a^3 + b^3 (1)
