Using the quadratic formula to solve x2 = 5 – X, what are the values of X? -1021
2
-1 + 19
2
5+21
2
1+ /19/
2

Step-by-step explanation:

Add x from both sides:

Subtract 5 from both sides:

Now, we'll use the quadratic formula to solve this problem:

Multiply 4*1*5= 20

Add 1 and 20= 21

Multiply 2 and 1= 2

Multiply 2 and 1= 2

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
