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

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
