First you bring the x to one side so u subtract 4x from 7x and you get the new equation as -9=3x+12 then you just solve and you get x is equal to -7
The two numbers are -6 and -20
-20 x -6 = 120
-20 + (-6) = -26

Answer:
x = 5 or x = 1
Step-by-step explanation:
x² - 6x + 7 = 0
x² - 6x = -7
x² - 6x + 9 = -7 + 9 1/2 of the x term than square it and add it the both sides.
(x - 3)(x - 3) = 2
( x -3)² = 2
= 
(x - 3) = ± 2
x - 3 = 2 or x - 3 = -2
x = 5 or x = 1
