What is the value of b^2 - 4ac for the following equation

2x^2 + 3x = -1

1

Step-by-step explanation:

We are finding the discriminant of the function

It needs to be written in the form  ax^2 +bx+c =0

2x^2 +3x = -1

Add 1 to each side

2x^2 +3x+1 = -1+1

2x^2 +3x+1 = -0

b^2 -4ac

a=2   b=3  and c = 1

3^2 - 4(2)(1)

9 - 8

1

In that quadratic equation:

a = 2  b = 3 and c = 1

b^2 -4*a*c equals

9 -4 * 2 * 1 =

9 -8=

1

step-by-step explanation:

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
