Question

select the approximate values of x that are solutions to f(x) = 0 where f(x)=-3x^2+2x+4

a- {-0.87, 1.54}

b- {-3,2}

c- {-0.67,-1.33}

d-{-0.75,0.50}

Answer 1

Set the equation formula equal to zero:

 

-3x²+2x+4=0

 

Use the quadratic formula to solve for x:

 

x=(-b±sqrt(b²-4ac))/(2a)

 

where a=-3, b=2, c=4
