Answer:

${b}^{2} + 3b - 3 = 0$

Step-by-step explanation:

${b}^{2} + 3b - 3 = 0 \\ because \: \: {b}^{2} < 4ac \\ {b}^{2} = {3}^{2} = 9 \\ 4ac = 4 \times 1 \times - 3 = - 12 \\ hence : {b}^{2} < 4ac$

Answer:

1. The two numbers are 4 and 8.

Step-by-step explanation:

1) variables: x and y

2) x + y = 12, y - x = 4

3) graph using desmos or another graphing calculator

4) the solution is x = 4, y = 8, or 4 and 8. This means that 4 and 8 can be added to equal 12, and the difference between them is 4.

Hello there,

1/18 + 1/x = 1/2
1/x = 9/18 - 1/18 
1/x = 8/18 = 4/9 
x = 9/4 or 2.25
