Your required answer :

______________________________________

Given :

• x² - x - 20 = 0

______________________________________

To find :

• Roots / Zeroes

______________________________________

Solution :

By middle term splitting :

• x² - x - 20 = 0
• x² + 4x - 5x - 20 = 0
• x ( x + 4 ) - 5 ( x + 4 ) = 0
• ( x - 5 ) ( x + 4 ) = 0

______________________________________

Now Zeroes / Roots :

• x - 5 = 0
• x = 5

______________________________________

• x + 4 = 0
• x = -4
