Answer:

x = -2

Step-by-step explanation:

If you factor out 1/9 you get rid of the fractions and that makes the equation a whole lot easier.

[tex](5x+10)^2 - x(25x+27) + 46 = 0[/tex]

Next, eliminate the brackets:

[tex]25x^2 +100x + 100 - 25x^2 - 27x + 46 = 0[/tex]

Combine the terms:

[tex]x = \frac{- 146}{73} = -2[/tex]

Answer:

x = - 2

Step-by-step explanation:

The 9 does absolutely nothing. Multiply the whole equation by. 9. Remember that each term must show the 9 is missing

(5x + 10)^2 - x(25x + 27)  + 46 = 0

Next expand the first and second binomial so that the brackets can be removed.

(25x^2 + 100x + 100) - (25x^2 + 27x) + 46 = 0  

Now remove the brackets

25x^2 + 100x + 100 - 25x^2 - 27x + 46 = 0

Collect the like terms

25x^2 - 25x^2 + 100x - 27x + 100 +46 = 0

73x + 146 = 0                

Subtract 146 from both sides

73x = - 146

Divide by 73

x = - 146/73

x = - 2     <<<<                Answer
