Hence the solution is a radius of 0.32 cm. We can check this value of 0.32 cm by substitution in the equation 2 = r2 + 6r. Hence 0.10 + 1.92 = 2.02, which is effectively 2 bearing in mind the rounding of the root value to two decimal places that has occurred. Problems 1.3 1 ...

The quadratic equation abx^2 + acx + b(bx + C) = 0 has non-zero equal and rational roots. The values of a and c respectively cannot be equal to (ab !=0)
In fact, when D is positive, we can write the equation as a difference of squares, and show that the left side can always be factored as a product of linear factors. From here, it is easy to argue that the solutions we have found are the only solution. Probably the first ...
Answer The reduced quadratic equation is 8t^2 + 2t + 2 = 0 with . Computing the discriminant shows that since it is 4 − 4(8)(2) < 0 that the reduced quadratic has no real solutions and therefore the original equation does not have any real solutions. The solution set is ...
解析 From the given we get△=(-4)^2-4(k-5)=36-4k.(1) Since the equation hastwo distinct real roots, △0 ; the solution is k9.(2) Since the equation has two equal realroots, △=0; the solution isk=9 (3) Since theequation has no real roots, △0 ; the solution isk9 . ...
