\frac{-b+-\sqrt{b^2-4ac} }{2a}; ax^2+bx+c \\ \\ a=1, b=-12, c=59

Use the formulas above to solve the equation.

1x^2-12x+59=0\\ \\ \frac{-(-12)+-\sqrt{(-12)^2-4(1)(59)} }{2(1)}\\ \\ \frac{12+-\sqrt{144-236} }{2}\\ \\ \frac{12+-\sqrt{-92} }{2}

Now this problem will be giving i values since there's a negative in the square root. These i's are known as imaginary numbers. For the answer it should be these two:

x =(12-\sqrt{-92})/2=6-i\sqrt{23} = 6.0000-4.7958i

x =(12+\sqrt{-92})/2=6+i\sqrt{23} = 6.0000+4.7958i

Let me know if you need help with finding i and all or if you just needed the answer to check your work. Hope this helps!

The product of 5 and a number X is 1/4
Sloan [31]

Hi!

5x = 1/4

5x = 0.25

<h3>Divide by 5 on both sides</h3>

5x/5 = 0.25/5

x = 0.05

<h3>Convert 0.05 to a fraction</h3>

5/100

<h3>Simplify the fraction</h3>

1/20

<h2>The answer is X=1/20</h2>

Hope this helps! :)
