anyone know what factors can be multipied to get -35 but added to gett -18

Question

anonymous · Answer

7 x 5 = 35

anonymous · Answer

however when added , they are not equal to 18

anonymous · Answer

yeah thought of that one but it doenst work on the second level

anonymous · Answer

x * y = -35
x + y = -18
x = -18 - y
Plug back in:
(-18-y)*y = -35
-18 y + y^2 = -35
y^2 - 18y + 35 = 0
y = around 15.78 ish
or y = about 2.13 ish
Then plug back for x.

wait, isn't it supposed to be

xy = 35 and x + y = 18?

Here are the exact values:

$$x = -9 - 2 \sqrt{29}$$
$$y = -9 + 2 \sqrt{29}$$
