Algebra Examples

f (x) = 6 x^{2} + x

$f (x) = 6 x^{2} + x$ ,

g (x) = x + 1

$g (x) = x + 1$ ,

f (x) - g (x)

$f (x) - g (x)$

Step 1

Replace the function designators in

f (x) - g x

$f (x) - g x$ with the actual functions.

(6 x^{2} + x) - (x + 1)

$(6 x^{2} + x) - (x + 1)$

Step 2

Simplify

(6 x^{2} + x) - (x + 1)

$(6 x^{2} + x) - (x + 1)$ .

$1$ .

6 x^{2} + x - x - 1

$6 x^{2} + x - x - 1$

6 x^{2} + x - x - 1

$6 x^{2} + x - x - 1$

Step 2.2

Combine the opposite terms in

6 x^{2} + x - x - 1

$6 x^{2} + x - x - 1$ .
