Question

5) Find the roots of the equation x²-3x- 10 = 0.​

Answer 1

Answer:

x = -2, 5

Step-by-step explanation:

x² - 3x - 10

= x² - 5x + 2x - 10

= x(x - 5) + 2(x - 5)

= (x + 2)(x - 5)

x = -2, 5

Hence solved

Answer 2

Answer:

- 2 and 5

Step-by-step explanation:

x² - 3x - 10 = 0

x² + 2x - 5x - 10 = 0

x ( x + 2 ) - 5 ( x + 2 ) = 0

( x + 2 ) ( x - 5 ) = 0

x + 2 = 0

x = - 2

x - 5 = 0

x = 5

Therefore, the roots of the given equation are - 2 and 5.
