Solve for x, rounding to the nearest hundredth.
550.3^ x = 50

- 2.18

Step-by-step explanation:

550 × = 50

=

= x

x = 1 - 11

1 = 0

11 = 2.1826583386

x ≈ - 2.18

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
