If f(x) = 2x2 + 3 and g(x) = x2 – 7, find (f – g)(x).

a. 3x2 – 4
b. x2 – 4
c. x2 + 10
d. 3x2 – 10

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2
