What times what equals -462 that adds up to equal 8?

Answer 1

-454

Answer 2

Let the numbers be 'm' & 'n'

Hence mn = -462

m + n = 8

m = 8 - n

Substitute

(n - 8)n = -462

n^(2) - 8n = -462

n^(2) -8n + 462 = 0

It is now in Quadratic form, Apply the Quadratic Eq'n.

n = { -8 +/-sqrt[(-8)^(2) - 4(462)(1)]} / 2(1)

n = { -8 +/-sqrt[64 - 1848]} / 2

n = ( -8 +/- sqrt[ - 1784]} / 2

This remains unresolved as you cannot take the square root of a negative number.

Answer 3

-17.8632 and 25.8632 (to 4 dp)

Another Answer:-

(4+sq rt of 478)*(4-sq rt of 478) = -462

(4+sq rt of 478)+(4-sq rt of 478) = 8
