Answer: M= 9,2 (Quadrant |||) L= -9,2 J= 9,6 K=-9,6
Step-by-step explanation:
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.
If we are solving for x then it would be -1 :)
Answer:
first use the Pythagoras theorem to find for a,b and c
that is. c²= b²+a²
then when you find the answers find the area of A,B and C
that is <u>1</u>× base × height
