Question

Identify the number of solutions and its type for the equation 3x2 − 5x + 19 = 0.

Answer 1

do you want the answer or help

Answer 2

um both

Answer 3

ok do you know how to solve it

Answer 4

no

Answer 5

the highest power is 2 so this is a quadratic equation.

Answer 6

1 real
2 nonreal complex
1 nonreal complex
2 real
so it would be 2 real?

Answer 7

those are the four multiple choices..

Answer 8

do you know the quadratic formula? and are you familiar with the discriminant?

Answer 9

no.. :/

Answer 10

the general form for a quadratic equation is ax^2 + bx + c = 0 where a, b, c are non-zero integers
the discriminant b^2 - 4ac will tell the type of solution

Answer 11

oh okies

Answer 12

let the discriminant = D
when D>0 2 real roots
when D = 0 1 same root
when D < 0 ( taking the square root of a negative ) then no real roots can be complex

Answer 13

to solve for x you can factor the equation or use the formula
