Answer:
Choice b is correct answer.
Step-by-step explanation:
Given equation is :
-4x²+10x+6 = 0
ax²+bx+c = 0 is general quadratic equation.
comparing general equation with given quadratic equation,we get
a = -4 ,b = 10 and c = 6
we use the discriminant formula to find number of solution.
If D > 0 then there is two real solutions.
The formula to find discriminant is :
D = b²-4ac
putting above values in discriminant formula, we get
D = (10)²-4(-4)(6)
D = 100+96
D = 196 > 0
hence , equation have two real equation.
