  1. (x^3+3)(x-1)=x^4-x^3+3x-3
    =x(x^3-x^2+3)-3
    =x-3=0.....eqn1
    =x^3-x^2+3=0...eqn2
    From eqn2 using a calculator u get
    X=-1.17,x=1.09,x=1.09
    From eqn1 u get x=3. U get 4 answer for this algebra because x is raised to the power 4 i.e x^4 when u open ur bracket.

    Solve the inequality. n-1/3n < n-4/3n-4 (it's actually less than or equal to) My first instinct is to multiply 3n, but that'll just give me squares and makes it harder to solve. I also thought about getting a common denominator,

    Can you please check my work? You have helped other students I know. Thank you:) Multiply -7(2a2 -4) = -14a2 + 28 Multiply 0.5(a + b -5) = 0.5a + 0.5b - 2.5 Factor bx - by + bz = b(x - y + z) Combine like terms (simplify) 12x + 4
