What is the discriminant of the quadratic equation 3 – 4x = –6x2?
–68
–56
76
88

.

Step-by-step explanation:

Given : -6x² = 3 -4x.

To find : What is the discriminant of the quadratic equation .

Solution : We have given that  -6x² = 3 -4x.

Rewrite the equation :  -6x²+ 4x -3 = 0.

Standard form of quadratic form  : ax²+ bx + c = 0.

Discriminant = .

Then, a = -6 , b =4 , c =-3

.

.

.

Therefore, .

the answer is 489

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
