Question

2 x -12x-18=0 знайти суму та добуток його коренів

Answer 1

сума = 12

добуток = -18

Answer 2

To find the sum and product of the roots of the quadratic equation 2x^2 - 12x - 18 = 0, we can use the following formulas:

For a quadratic equation of the form ax^2 + bx + c = 0:

1. The sum of the roots (x1 and x2) is given by: Sum = -b/a
2. The product of the roots (x1 and x2) is given by: Product = c/a

In the given equation, a = 2, b = -12, and c = -18.

1. Sum of the roots: Sum = -(-12) / 2 = 12 / 2 = 6

2. Product of the roots: Product = (-18) / 2 = -9

So, the sum of the roots is 6, and the product of the roots is -9.
