okay first bring everything to one side so your equation = 0
now do you know what the quadratic formula is?
this is it. now bring everything to the left in your equation
I don't understand how
okay, this is your equation --> x^2+3=-4x now im going to bring everything to the left --->\[x^2+4x+3=0\]
Okay, now what?
now this is the general formula for a quadratic ax^2+bx+c so now what from your equation is a, b and c?
I have no clue
okay here ill give you an example in this equation 2x^2 + 3x + 5 a=2 b=3 and c=5 in this equation 6x^2+9x+12 a=6 b=9 and c=12
so for x^2+4x+3 what is a, b and c?
a=2 b=4 c=3?
b and c are right but a=1 remember x^2 is really 1x^2. and its general formula is ax^2 so a=1
but yes a=1 b=4 and c=3 now just sub these into the quadratic equation that I gave you above
k hold on i'll try
sure, you shpuld get two answers
what does the plus sigh with the line under it mean?
lol because you have to get two answers for x (as it is a parabola and will intersect at the x axis in two place)s there are actually two quadratic equations
one is -b + so on and the other is -b - something
so what are your answers that you get?
1 and 3
its actually -1 and -3
oh oops. Thank you
no problem, glad to help!
