Select the correct answer from each drop-down menu. determine the number of real solutions for each of the given equations. equation number of solutions y = -3x2 x 12 y = 2x2 - 6x 5 y = x2 7x - 11 y = -x2 - 8x - 16

Respuesta :

It should be noted that in the equation y = -3x² + x + 12, there are two real solutions.

How to calculate the real solutions?

It should be noted that the number of real solutions of a quadratic equation is represented by y = ax² + bx - c.

In the equation, equation y = -3x² + x + 12, the coefficients are a = -3, b = 1 and c = 12. The discriminant will be:

= 1² - 4(-4)(12)

= 145

It is positive, therefore, it has two solutions.
