What polynomial should be subtracted from 7x2−6x+5 to get the difference equal to x2−x.

 should be subtracted from to get the difference equal to  

Step-by-step explanation:

Here, the given polynomial  

And, The other Polynomial

Let us assume there exists a polynomial Q(x) such that the difference of P(x) and Q(x) is R (x):

⇒P(x) - Q(x)  = R (x)

Hence,  should be subtracted from to get the difference equal to  

can you put the picture up?

step-by-step explanation:

x =-.20752

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
