The function g(x) is defined as g(x) = −2x^2 + 3x. The value of g(−3) is

g(-3) = -27

Step-by-step explanation:

g(x) = -2x² + 3x ---> g(-3)

g(-3) = -2(-3)² + 3(-3)

g(-3) = -2(9) + 3(-3)

g(-3) = -18 - 9

g(-3) = -27

Hope this helps, thank you :) !!

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.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
