Using the quadratic formula to solve 2x^2 = 4x - 7, what are the values of x?

The values of x are

Step-by-step explanation:

The quadratic formula is:

Our equation is:

a= 2, b= -4 and c =7

Putting the values in quadratic formula:

Since we have -40 in the under root we will find its factors and simplify:

Factors of 40 = 2*2*2*5

The values of x are:

answer: i don't understand. what are the options

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
