The answer:
the main formula which should be used to reply this is:
g(x) - h(x) = (g-h) (x)
if the question does mean <span> g(x) = 3(2 ^ x )
</span>
k(x)= (g – h)(x) = 3(2 ^x ) - 2 ^(x+1)
and we know that because of a^x+p = a^*a^p
=3(2 ^x ) - 2 ^(x)2^1=(2 ^x )(3 - 2^1)
=(2 ^x )(3 - 2^1)= 2 ^x
the answer is <span>k(x) = 2^x</span>
The error is in the first step. It should be (+8 plus or minus the square root of the quantity eight squared minus four times one times seven ). This is because "b" is -8 so -b is -(-8) = +8
You follow the rule PEMDAS parenthesis, exponent, multipy, divide, add, substart. So you would start off by doing 27-12x2, you would do 12x2=24 first then 27-24=3. So then it would be 4+3/2, do 3/2=1.5, then add it 4+1.5=5.5. So the correct answer is 5.5
