Using the quadratic formula, you can solve this quite easily.,,,,
a      b       c
x² - 12x + 59 = 0              a(1)...b(-12).....c(59)

(-b +/- √b² - 4ac) / (2a)      (substitute the values for a, b, and c)
(-(-12) +/- √ (-12)² - 4 (1) (59)) / 2(1)
(12 +/- √-92) / 2                  ( √-92 can be written as √-1√4√23)
(12 +/- √-1√4√23) / 2          (√-1 = i and √4 = 2)

6 +/- 23i

Sidana [21]

Answer:

Area of ΔDEF = 12 in²

Step-by-step explanation:

Since they are similar, we have to find the scale factor

Scale Factor = \frac{Side OfDilated Triangle}{Side of Original Triangle}

Scale Factor = 4/2

Scale Factor = 2

<u><em>This means The area of ΔABC is 2 times the area of ΔDEF</em></u>

So,

ΔABC = 2(ΔDEF)

Where Area of ΔABC = 24 in²

24 = 2(ΔDEF)

Dividing both sides by 2

=> Area of ΔDEF = 12 in²
