X ^ 2 + 4x - 7 = 0<br><br> Solve using the Quadratic Formula
aalyn [17]

There's a special case of the quadratic formula called the Shakespeare Quadratic Formula (2b or -2b) that applies when the linear coefficient is even.

x^2-2Bx + C \textrm{ has zeros }x = B \pm\sqrt{B^2 - C}

If you're planning on solving a lot of quadratic equations quickly, it's good to know.

Here we have

x^2 + 4x - 7 = 0

so

x = -2 \pm \sqrt{2^2 - -7}

x = -2 \pm \sqrt{11}

Troyanec [42]
The tree diagram of the problem above is attached
There are four outcomes of the two events,

First test - Cancer, Second Test - Cancer, the probability is 0.0396
First test - Cancer, Second Test - No Cancer, the probability is 0.0004
First test -  No Cancer, Second Test - There is cancer, the probability is 0.0096
First test - No cancer, Second Test - No cancer, the probability is 0.9054

The probability of someone picked at random has cancer given that test result indicates cancer is  \frac{0.0396}{0.0396+0.0096}= \frac{33}{41}

The probability of someone picked at random has cancer given that test result indicates no cancer is \frac{0.0396}{0.0004+0.9504} = \frac{99}{2377}
