Question

the sum of two integer is -11 and their product is -60 what are the two integers​

Answer 1

Answer:

4 and -15

Step-by-step explanation:

let those two integers are a and b

a + b = -11

a*b = -60

a = -60/b

-60/b +b = -11

-60 + b² = -11b

b²+11b-60 = 0

b²+15b-4b-60 = 0

b(b+15) - 4(b+15) =0

b= 4 and -15

a = -60/4 = -15

and -60/-15 = 4
