WebPolynomial Roots Calculator found no rational roots . Equation at the end of step 1 : x 2 + 8 = 0 Step 2 : Solving a Single Variable Equation : 2.1 Solve : x 2 +8 = 0 Subtract 8 from both sides of the equation : x 2 = -8 When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get: Web1 Answers. (a) We can use the difference of cubes factorization to solve for ab: Substituting a2+ab+b2=13 and a−b=4 into the quadratic formula, we get: Therefore, the possible values of ab are −2isqrt (7),2isqrt (7) ,−4,4 . (b) We can use the sum of cubes factorization to solve for a+b: (c) Since we already found that ab can take on the ...
