Finding the discriminate of a quadratic formula determines the number and type of answers.
The formula is b^2 -4(ac)
a = 6. b = -7 and c = -4
-7^2 -4(6*-4) = 145
The answer is a positive number so this means there are 2 real solutions.
Answer:
two real solutions
Step-by-step explanation:
We can use the discriminant to determine the type and number of solutions
b^2 -4ac where ax^2 +bx +c
If b^2 -4ac > 0 we have 2 real solutions
b^2 -4ac = 0 there is 1 real solution
b^2 -4ac < 0 there are 2 complex solutions
6x^2 -7x -4 = 0
a=6 b =-7 c = -4
b^2 -4ac
(-7)^2 -4(6)(-4)
49 + 96
145>0
There are real solutions
60
