Question

Write the sum and the product of the root of 2xsquare+10x-5=0

Answer 1

Sum = -5.

Product = -2.5.

Explanation:

For the general form ax^2 + bx + c = 0, the sum of the roots = - b/a and the product of the roots = c/a.

We have 2x^2 +10x - 5 = 0 so and the sum = -10/2 = -5 and the product = -5/2 = -2.5.
