Answer:
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
Answer:
a = ±b
Step-by-step explanation:
The vertical bars are the symbol for "absolute value", so the equation is saying, "the absolute value of 'a' is equal to the absolute value of 'b'." The absolute value is the magnitude of a number, so, for example, |-3| = 3.
If the magnitudes of two numbers are the same, they may be the same value, or they may differ in sign.
