What is the discriminant of the quadratic equation 0 = 2x2 3x – 5? –37 –31 43 49

Degger [83]

The discriminant of a quadratic equation is useful in determining the nature of its roots. Further, it can be solved by the equation,
D = b² - 4ac
From the given equation, b = 3, a = 2, and c = -5. Substituting the given to the equation,
D = 3² - (4)(2)(-5) = 49
Thus, the answer is the fourth choice, 49.

aniked [119]

Answer:

Product: $(3a-1)(3a-1)$

Polynomial: $9a^{2} -6a+1$

Step-by-step explanation:

$(3a-1)^{2}$ is equal to $(3a-1)(3a-1)$ . Then, expand it using the distributive property to get $9a^{2} -3a-3a+1$ which, simplified is $9a^{2} -6a+1$ .
