Question

Find two integers whose sum is -7 and whose product is 12.

Answer 1

Answer:

-4 , -3

Step-by-step explanation:

-4 + ( -3 )

-4 - 3 = -7

-4 * -3 = 12

Answer 2

Answer:

-4, -3

Step-by-step explanation:

Let the integer be x and y

Thus

X+y= -7 ------(1)

Xy=12--------(2)

X=-7- y

(-7-y) y=12

-7y-y²=12

-y²-7y-12=0

-y²-(3+4) y-12=0

-y²-3y-4y-12=0

-y(y+3) -4(y+3) =0

(-4-y) (y+3) =0

-y=4 and y+3

Y= -4 and y= -3
