Polynomial equation: x3 + 6x2 - 40x = 192

ankoles [38]

If we substitute the correct value of x into the right side of the given expression, it should yield 192.

Test x = -8
(-8)^3 + 6(-8)^2 - 40(-8) = 192 Correct
Test x = -4
(-4)^3 + 6(-4)^2 - 40(-4) = 192 Correct
Test x = 6
6^3 + 6(6^2) - 40(6) = 192 Correct

All solutions make sense, so none of them should be eliminated.

Can someone explain to me how to solve it?

lions [1.4K]

Step-by-step explanation:

The problem is basically asking for the roots, or the x-intercepts. To do this, follow the quadratic formula:

b is the second coefficient(+13)

a is the first coefficient(5)

c is the third coefficient(-6)

When the formula is negative, it just means to flip the sign from a positive to negative or negative to positive. Plug in and simplify.
