Given:
• x² - 3x - 1
To find :
• The equation whose zeroes are
Solution :
•f (x) = x² - 3x - 1
Now , compare with ax² + bx + c we get :
• a = 1 , b = -3 and c = -1
Now , to find the equation whose zeroes are :
As we know that :
• F (x ) = x² - ( sum of Zeroes ) x + product of zeroes
=> x² - (-3)x + (-1)
=> x² + 3x -1 .
