kkurt [141]3 years ago
4 0

Answer:

x = 2 \:  \:  \:  \:  \: or \:  \:  \:  \:  \: x =  - 11

Step-by-step explanation:

{x}^{2}  + 9x - 22 = 0 \\  {x}^{2}  + 11x - 2x - 22 = 0 \\  x(x + 11) - 2(x + 11) = 0 \\ (x - 2)(x + 11) = 0 \\ x - 2 = 0 \:  \:  \:  \:  \: or \:  \:  \:  \:  \: x + 11 = 0 \\ x = 2 \:  \:  \:  \:  \: or \:  \:  \:  \:  \: x =  - 11

You can do this a number of ways.
The first way is to set up a proportion. That's very formal, and is most respected.

Proportion.
x / 60 = 1 / 10 The proportion is reduced by a factor of 10. Cross Multiply.
10 * x = 60 * 1 
10x = 60  Divide by 10
x = 60/10 
x = 6

Multiply by the scale factor.
Beginning number * scale factor = Final result.
60 * 1/10  = Final Result
60 * 1 / 10 = Final Result
Final Result = 6

This method words even when the numbers are quite complicated.
