When f(x) = x2+9 and g(x) = x-9, find f(x)-g(x).

ohaa [14]

Answer:

$\huge{ \boxed{ \sf{ {x}^{2} - x + 18}}}$

Step-by-step explanation:

$\underline{ \text{Given}}:$

$\sf{f(x) = {x}^{2} +9 \: and \: g(x) = x-9}$

$\underline{ \text{To \: find}} : \sf{ \: f(x) \: - \: g(x)}$

Put the values:

$\mapsto{ \sf{ {x}^{2} + 9 - ( x - 9)}}$

While subtracting , sign of each term of the second expression changes.

$\mapsto{ \sf{ {x}^{2} + 9 - x + 9}}$

Add the numbers : 9 and 9

$\mapsto{ \boxed{ \sf{{x}^{2} - x + 18}}}$

Hope I helped!

Best regards! :D
