If the square of a number plus eight times the number, the sum is twenty. what is the number? what is the formulated equation? what are the factors of the quadratic equation? what is the positive root?
The numbers are -10 and 2. The equation will be x² + 8x = 20. Transposing the 20 to the other side, it will now become x² + 8x - 20 = 0. Thr factors of this equation are (x+10) (x-2). The positive root is 2.
