Use the discriminant to find the number of real solutions of the equation 3x2 – 5x + 4 = 0. Show your work.
3^2-5x+4=0
I mean 3x^2
a quadratic equation is in the form of ax^2+bx+c=0. The discriminant is determined from the coeffcients of your quadratic equation. D=b^2-4ac
a=3 b=-5 c=4
b^2-4ac < 0 means there are no real roots b^2-4ac = 0 means equal real roots b^2-4ac > 0 means there are distinct real roots
wat to do next
use the quadratic formula to find the roots of your quadratic equation but before doing that calculate your discriminant.
b^2-4ac (-5)^2-4(3)(4)=-23 -b+-(b^2-4ac)^1/2/2a -5+(-23)^1/2/2*3 or -5-(23)^1/2/2(3)
is that right Use the discriminant to find the number of real solutions of the equation 3x2 – 5x + 4 = 0. Show your work. b^2-4ac (-5)^2-4(3)(4)=-23 -b+-(b^2-4ac)^1/2/2a -5+(-23)^1/2/2*3 or -5-(23)^1/2/2(3)
