what factors add up to -132 and multiply together to -132

Question

what two numbers add up to -132 and can be multiplied together that equal -132

Answer 1

x+y = -132

xy = -132

x = -132-y

(-132-y)y =-132

-132y-y^2 =-132

y^2 + 132y + 66^2= 132+66^2

(y+66)^2 = 4488

y = -66 + or - sqr4488

y = -66 + or - 66.993

y = -132.993 or +.993

the two numbers are 0.993 and -132.993

they sum to -132

their product is -132 approximately

You could see approximately this solution by noticing -132 and 1 sum to -133 and their product is -132

the numbers are very close to -133 and +1
