Find all real zeros of tf(x)=x-14x² + 47x-18​

Mathematics
1 answer:
BabaBlast [244]3 years ago
4 0

Answer:

x=3/7 and x= 3

Step-by-step explanation:

First simplify:

-14 x^2 +48x -18

divide everything by -2

-2(7 x^2 -24x +9) (Multiply the leading coefficient 7 by the constant 9)

-2 (x^2 -24x +63)

-2 [(x-3)(x-21)] Now divide the 7 that you multiplied earlier from 3 and 21

-2 [(x-3/7)(x-21/7)]

-2 [(7x-3)(x-3)]

Hence, the zeroes are 3/7 and 3

Hope this helps!

I need help with this math problem!!
Vesnalui [34]
In order to find which one is or isn't, you need to solve for the value of 'x'. 
2x + 15 = 35 
2x = 20
x = 10 

Substitute x =10, into equation. If each side are not the same (i.e. 0=2), then that's the equation that is not equivalent,

Answer is B
Double check this. Chur! :)

Hope this makes sense.
