The equation given above is written here below with all the terms transposed to only one side of the equation.
2x² + 3x + 8 = 0
The quadratic formula used for the determination of the roots is,
x = (-b +/- sqrt (b² - 4ac)) / 2a
In the quadratic equation above, we have the numerical coefficients.
a = 2
b = 3
c = 8
Substituting the known values,
x = (-3 +/- sqrt (3² - 4(2)(8))/ (2)(2)
x = -0.75 + 1.854i and x = -0.75 - 1.854i
By the calculated roots above, it is known that the roots are imaginary.
Answer:
5x³ + 5x² - 55x - 15
Step-by-step explanation:
simplify the expression:
5(x − 3)(x² + 4x + 1)
use the distributive property to multiply 5 by x-3
(5x - 15) (x² + 4x + 1)
Use the distributive property to multiply 5x−15 by x²
+4x+1 and combine like terms
5x³ + 5x² - 55x - 15
