Question

X2+6x-55=0 ответ должен получится -55

Answer 1

Как там может получиться -55?

Answer 2

$x^2+6x-55=0 \\ x_1+x_2=-6 \\ x_1*x_2=-55 \\ x_1=-11 \ \ \ x_2=5$
-11*5=-55

Answer 3

To find the sum of the solutions (roots) of the quadratic equation x^2 + 6x - 55 = 0, you can use Vieta's formulas. The sum of the roots (solutions) of a quadratic equation ax^2 + bx + c = 0 is given by -b/a.

In this case, the coefficient of x^2 is a = 1, and the coefficient of x is b = 6. Therefore, the sum of the solutions is:

Sum of solutions = -b/a = -6/1 = -6

So, the correct answer is -6, not -55.
