The correct answer is answer for that question is f(x) = (2,0)
Explain
F(x)= 2x^2 -14x+20
When f(x) = 0
Take out the 2
2(x^2-7x+10) = 0
Now divide by 2
X^2 -7x+10 = 0
Splitting = -7x= -5x-2x
X^2-5x -2x+10=0
Take x common from -2 as 2
X(x-5)-2(x-5)= 0
Take (x-5) common
(X-5)(x-2)0
X-5=0 x-2=0
X=5. X=2
Now zero of g(x) is 0 at x=19
Which is at x= 2 f(x ) =0
I hope this help you :D
