Answer 1

Answer:

it must be correct✅✔✅✔✅✔✅

Answer 2

The roots of the equation x²-x-2 = 0 are 2 and -1.

Given,

A quadratic equation x²-x-2 = 0.

To Find,

The roots of the equation.

Solution,

The given quadratic equation is

x²-x-2 = 0

Using the middle-term splitting method

x²-x-2 = 0

Splitting the middle-term -x as -2x+x

x²-2x+x-2 = 0

x(x-2)+1(x-2) = 0

(x-2)(x+1) = 0

x = 2 or -1.

Hence, the roots of the equation x²-x-2 = 0 are 2 and -1.
