x² - 4x - 60 = 0
We need to split the middle term (i.e., -4) , in such that the product of the numbers should be -60 and sum of them -4
Numbers are 10 and -6
→ x² - 4x - 60 = 0
→ x² - 10x + 6x - 60 = 0
→ x(x - 10) + 6(x - 10) = 0
→ (x + 6)(x - 10) = 0
If x + 6 = 0
→ x = - 6
else if x - 10 = 0
→ x = 10
Solution :- x = -6 or 10
