Question

One of the roots of a quadratic equation x2 -x + m = 0 is -2, therefore the value of m is?
(6, 2 -6, -2)

Please give me a step by step explanation, would be greatful. The right answer will surely be marked as the brainliest.

​

Answer 1

Answer:

m= -6

Step-by-step explanation:

x²-x+m=0  

-2 is one of the root of this equation

Means, x=-2

putting the value of x as-2 in equation

(-2)²-(-2)+m=0

4+2+m=0

6+m=0

m= -6

Answer 2

Answer:

x = -2 is one of the roots of given equation.

Put x = -2 in the given equation x² - x + m = 0

(-2)² - (-2) + m = 0

4 + 2 + m = 0

6 + m = 0

m = -6

Here's your answer...
