Question

9. Solve the equation:
x2 -(x+1)(x+2)/5x+1​

Answer 1

Answer:

x = -2/3

Read the brief explanation ...

Step-by-step explanation:

= x² - (x+1)(x+2) / 5x + 1

= x² - (x² + 2x + x + 2) / 5x + 1

= x² - x² - 3x - 2 / 5x + 1

= -(3x + 2)/5x +1

if it is equal to zero then ,

=> -3x-2 = 0×(5x+1)

=> -3x = 2

=> x = -2/3
