Answer from: dlatricewilcoxp0tsdw

ther are two solutions

1. x = -5

2. x = -12

Step-by-step explanation:

-60 + -1 = -61

-30 + -2 = -32

-20 + -3 = -23

-15 + -4 = -19

-12 + -5 = -17

-10 + -6 = -16

-6 + -10 = -16

-5 + -12 = -17

-4 + -15 = -19

-3 + -20 = -23

-2 + -30 = -32

-1 + -60 = -61

1 + 60 = 61

2 + 30 = 32

3 + 20 = 23

4 + 15 = 19

5 + 12 = 17

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 5 and 12

x2 + 5x + 12x + 60

Step-4 : Add up the first 2 terms, pulling out like factors :

x • (x+5)

Add up the last 2 terms, pulling out common factors :

12 • (x+5)

Step-5 : Add up the four terms of step 4 :

(x+12) • (x+5)

Which is the desired factorization

the two solutions are:

x =(-17+√49)/2=(-17+7)/2= -5.000

or:

x =(-17-√49)/2=(-17-7)/2= -12.000

Answer from: Quest

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: $\sqrt{\frac{ {72x}^{16} }{ {50x}^{{{36} }}}} = \frac{ { \sqrt{72}x}^{ {16}^{ (\frac{1}{2}) } } }{ { \sqrt{50} x}^ {{36}^{ (\frac{1}{2}) } }}$ multiply exponents per exponent rules to get: $\frac{ { \sqrt{72}x}^{8} }{ { \sqrt{50}x}^{18} }$ remember you subtract exponents from the denominator and add exponents in the numerator so: $\sqrt{ \frac{72}{ 50}} \times ( {x}^{(8 - 18) } ) = \sqrt{ \frac{36}{25} } \times ( {x}^{ - 10} )$ simplify further: $\frac{6}{5} {x}^{ - 10} = \frac{6}{5 {x}^{10} }$ so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
