Solve 3x2 + 6x = 8. a. 1 plus or minus 2 square root 33
b. the quantity of negative 3 plus or minus I square root 15 all over 3
c. the quantity of negative 3 plus or minus square root 33 all over 3
d. 1 plus or minus 2 i square root 15

The quantity of negative 1 plus or minus square root 33 all over 3

Step-by-step explanation:

3x2+6x=8

3x^2+6x-8=0

Quadratic formula

x=-b +or-√b^2-4ac/2a

a=3

b=6

c=-8

x=-b +or-√b^2-4ac/2a

=-6 +or- √(6)^2 - 4*3*-8/2*3

=-6 +or- √36-(-96)/6

=-6 +or-√36+96/132

=-6 +or- √132/6

=-6 +or- 2√33/6

=-6/6 +or- 2√33/6

= -1 +or- √33/3

The quantity of negative 1 plus or minus square root 33 all over 3

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
