Answer:
The roots of the equation x² - 3x - 10 = 0 are B) 5 and -2.
Step-by-step explanation:
Given :-
x² - 3x - 10 = 0
To find :-
Roots of the equation.
Solution :-
x² - 3x - 10 = 0
x² - 5x + 2x - 10 = 0
x(x - 5) + 2(x - 5) = 0
(x - 5) (x + 2) = 0
x = 5 or x = -2
∴ The roots of the equation x² - 3x - 10 = 0 are 5 and -2.
