Write two numbers that multiply to the value on top and add to the value on bottom. -60−60 -4−4 \times× ++
yan [13]

Answer:

The two numbers are 6 and -10

Step-by-step explanation:

Given

Product = -60

Sum =-4

Required

Two numbers that satisfy the above

Let the two numbers be x and y.

So:

x * y = -60

x + y = -4

Make x the subject

x = -4 - y

Substitute x = -4 - y in x * y = -60

(-4 -y) * y = -60

Open bracket

-4y -y^2 = -60

Rewrite as:

y^2 + 4y - 60 = 0

Split

y^2 + 10y - 6y - 60 = 0

Factorize

y(y + 10) - 6(y + 10) = 0

Factor out y + 10

(y - 6) (y + 10) = 0

Solve for y

y -6=0\ or\ y+10=0

y =6\ or\ y=-10

Recall that:

x = -4 - y

So:

x = -4-6= -10

or

x = -4--10= 6

So:

y =6\ or\ y=-10

x = -10\ or\ x =6

<em>The two numbers are 6 and -10</em>
