Answer 2

Answer:

After factorizing we will get x = -15 and -4

Step-by-step explanation:

We are given the expression x²+19x+60=0 if we compare to a general quadratic equation, which is of the form ax²+bx+c=0

We will see that here c=60

While factorizing we need to consider this c

if c is a positive quantity then we need to break bx in such a way that the 2 quantities we are breaking can give  when multiplied and b when added

as c=60

Let's factorize this we will get 15,4 now if we multiply 15 and 4 we will get 60 and if we add we will get 19

Thus we can also write the given expression as

x²+15x+4x+60=0

or, x(x+15) + 4(x+15) = 0

or, (x+4)(x+15)=0

or, x = -4, -15
