Question

Determine the number and type of solutions

Answer 1

Determine the number and type of solutions for x2 + 4x + 3=0

Answer 2

x^2+4x+3=0

Answer 3

Quadratic equations has two solutions

Answer 4

Unless it is perfect square

Answer 5

2 Rational?

Answer 6

Since , b^2 -4ac >0 two rational solution

Answer 7

Compare your Quadratic equation with ax^2+bx+c=0
find a,b,c.
calculate b^2-4ac
if b^2-4ac is positive -----> 2 real roots.
if b^2-4ac is 0---->1 repeated real root.
if b^2-4ac is negative ---->2 imaginary roots..

Answer 8

what about this one? What is the range of the graph of y = (x – 4)^2 + 3?

Answer 9

@sauravshakya b^2-4ac>0 doesnt mean roots are rational.

Answer 10

if b^2-4ac is perfect square -----> 2 rational roots.

Answer 11

I mean real solutions

Answer 12

ok so its what i though, 2 rational
can someone help me on my other question
