Question

. Given the quadratic function f(x) = x2 – 6x + 9, find a value of x such that f(x) = 25.

Answer 1

x2-6x+9=25
x2-6x-16=0
solve the quadratic eq

Answer 2

by using factorize
(x-8)(x+2)=0
x-8=0
x=8
x+2=0
x=-2

Answer 3

im confused

Answer 4

the question say wan to find the x such that f(x)=25
since f(x)=x2-6x+9
and f(x)=25
we combine it bcome x2-6x+9=25

Answer 5

oh ok

Answer 6

f(x) = x^2 – 6x + 9 = 25 (According to the question)
\[x^2 -6x+9-25=0\]\[x^2-6x-16=0\]\[(x-8)(x+2) = 0\](Factorized)
x=8 or x=-2

Answer 7

thanks guys
