Question

find the roots of quadratic equation – 3x2+5x+12=0
by using quadratic formula ?​

Answer 1

Step-by-step explanation:

3x²+5x+12=0

Now,

we have the quadratic formula,

x=(-b±√(b²-4ac))/(2a)

x=(-5±√(5²-4(3)(12))/((2)(3))

x=(-5±√(25-144))/6

x=(-5±√119)/6

so the roots are,

x = ( -5 + √119 )/6

x = ( -5 - √119 )/6

This are the roots, don't worry I left space in between for more clear...
