Answer: f (x) = 3x2+30x+65

Step-by-step explanation:

F (x) = 3 (x+5) 2-10

Using bodmas

B = bracket

O=of

D = division

M = multiplication

A = Addition

S = subtraction

So we go with the bracket

(X+5) 2

= (x+5) (x+5)

Open the bracket

=x2+5x+5x+25

=x2+10x+15

Substitute for (x+5) 2

F (x) = 3 (x2+10x+25) - 10

Open the bracket

F (x) = 3x2+30x+75-10

F (x) = 3x2+30x+65
