Question

+find the discriminant and the number of real roots for this equation 9x^2+12x+14

Answer 1

Answer:

no real roots

Step-by-step explanation:

9x²+12x+14

recall that for a quadratic equation ax²+bx+c, the discriminant = b²- 4ac

In our case,

discriminant,

= b²- 4ac

= 12² - 4(9)(14)

= 144 - 504

= -360

because the discriminant is negative, there are no real roots.

Answer 2

Answer:

the number of real roots for this equation 9x^2+12x+14 is :

0 (zero)

Step-by-step explanation:

Let Δ represent the discriminant

Δ = b² - 4ac = 12² - 4(9)(14) = -360

since Δ < 0 then it doesn’t have any real root.
