4x + 20
x2+x-380 = (x+20)(x-19) when factored
The solutions are: x = 4, y = 2 and x = -4, y = -2
36. 4 squared is 16...16 + 20 - = 36.
-5 + (-4) - 12 - 20 - (-10) + 6 = -25
4x + 20
x - 2
Factor out -2: -2(x squared +11x-20). This is fully factored.
answer is p/5. problem: {[(p^2)-3p]/[(p^2)-6p+9]}/{20/(4p-12)}
x2+x-380 = (x+20)(x-19) when factored
-20 negative 20 minus 20
x2 - 9x + 20 = (x - 4)( x - 5)
(x - 5)(x + 4)
3x^2=-20 so x^2=-20/3 this has no real roots but the plus of minus i(square root of 20/3) is a solution if we allow complex numbers.
62 - 16 = 20
The solutions are: x = 4, y = 2 and x = -4, y = -2
36. 4 squared is 16...16 + 20 - = 36.
