If f(x)=3x^2+2 and g(x)=x^2-9 find (f-g)(x)
miss Akunina [59]

Here given, f(x) = 3x^2+2 and g(x) = x^2-9

we have to find (f-g)(x) which means the subtracting of the functions f(x) and g(x).

(f-g)(x) = f(x) - g(x)

= (3x^2+2) - (x^2-9)

= 3x^2+2 -x^2-(-9)

= 3x^2-x^2+2+9 ( we know that multiplication of negative and negative is positive)

= 2x^2+2+9

=2x^2+11

We have got the required answer here.

(f-g)(x) = 2x^2+11

How can i solve 2×2+16x+y+34=0
IRISSAK [1]
PEMDAS
multiply 2x2=4 and simplify the equation by looking for like terms to combine.

4+16x+y+34=0

4 and 34 are like terms so add them. 
the simplified expression is 16x+y+38
