Answer:
whl i think my bad if thats wrong
Answer:
The correct option is (A) No real solution.
Step-by-step explanation:
The expression provided is a quadratic equation.

The roots of a quadratic equation are:

Here,
a = 8
b = -10
c = 15
The conditions to determine real and complex roots are:
- If
then the quadratic equation has two complex roots. - If
then the quadratic equation has two real roots.
Compute the value of
as follows:

The equation has two complex roots.
Thus, the correct option is (A).
Answer:
x=10,−10
simple, it could be negative OR positive :D
Answer:
f(x)-g(x)=5x^3-17x^2+4 which appears as option A
Step-by-step explanation:
Simply subtract the function's expressions as shown below, and combine like terms to express the final result:
![f(x)=7x^3-10x^2-5\\g(x)=2x^3+7x^2-9\\f(x)-g(x)=7x^3-10x^2-5-[2x^3+7x^2-9]\\f(x)-g(x)=7x^3-10x^2-5-2x^3-7x^2+9\\f(x)-g(x)=7x^3-2x^3-10x^2-7x^2-5+9\\f(x)-g(x)=5x^3-17x^2+4](https://tex.z-dn.net/?f=f%28x%29%3D7x%5E3-10x%5E2-5%5C%5Cg%28x%29%3D2x%5E3%2B7x%5E2-9%5C%5Cf%28x%29-g%28x%29%3D7x%5E3-10x%5E2-5-%5B2x%5E3%2B7x%5E2-9%5D%5C%5Cf%28x%29-g%28x%29%3D7x%5E3-10x%5E2-5-2x%5E3-7x%5E2%2B9%5C%5Cf%28x%29-g%28x%29%3D7x%5E3-2x%5E3-10x%5E2-7x%5E2-5%2B9%5C%5Cf%28x%29-g%28x%29%3D5x%5E3-17x%5E2%2B4)
