Need to figure this out right now can somebody me? ~ find a quadratic equation with roots -1+4i and -1-4i

c

Step-by-step explanation:

Given the roots are x = - 1 + 4i and x = - 1 - 4i then the factors are

(x - (- 1 + 4i))(x - (- 1 - 4i))

= (x + 1- 4i )(x + 1 + 4i )

= (x + 1)² - 16i² → [ i² = - 1 ]

Expand and simplify

= x² + 2x + 1 + 16

Hence

x² + 2x + 17 = 0 → c

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
