Question Simplify the expression −1−3x−3x2−x3 Evaluate (−1−x)3A negative base raised to an odd power equals a negative −(1+x)3Expand the expression More Steps Evaluate (1+x)3Use (a+b)3=a3+3a2b+3ab2+b3 to expand the expression 13+3×12×x+3×1×x2+x3Calculate 1+3x+3x2+x3 −(1+3x+3x2+x3)Solution −1−3x−3x2−x3 Show Solution Factor the expression −(1+x)3 Evaluate (−1−x)3Factor the expression (−(1+x))3Solution −(1+x)3 Show Solution Find the roots x=−1 Evaluate (−1−x)3To find the roots of the expression,set the expression equal to 0 (−1−x)3=0The only way a power can be 0 is when the base equals 0 −1−x=0Move the constant to the right-hand side and change its sign −x=0+1Removing 0 doesn't change the value,so remove it from the expression −x=1Solution x=−1 Show Solution
