What is the solution to the following equation?
x^2 + 3x + 7 = 0

answer:

c. -3+√-19 /2

*i don't have the plus and minus symbol, but know that the addition sign is referring to the plus and minus symbol!

step-by-step explanation:

1) input the numbers to the quadratic formula

-3+√(3)^2-4•1•7/1•2

2) simplify

-3+√-19 /2

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
