Answer:
x=1+2i/2
Step-by-step explanation:
Using the method of completing the square
(2x)²-2(2x)1 +(1)²+4=0
(2x-1)²=-4
taking square root on both sides
2x-1=2i
2x=1+2i
x=1+2i/2
Because you didn't give the line, it is impossible to write it completely. However, the line would be y - 1 = m(x + 3), in which m is the slope in the line.
We know this firstly because parallel lines have the same slope. So whatever the slope is to the given line, it must match the point-slope form.
So, we'll call this mystery slope m and then use the point in plug in the point into point-slope form.
y - y1 = m(x - x1)
y - 1 = m(x - -3)
y - 1 = m(x + 3)
Answer:
Answer A
Step-by-step explanation:
slope= (c+d-(c-d))/(c-d-(c+d))=2d/(-2d)=-1
2x2 + -4x + -3 = 0 Reorder the terms: -3 + -4x + 2x2 = 0 Solving -3 + -4x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -1.5 + -2x + x2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + -2x + 1.5 + x2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + -2x + x2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + -2x + x2 = 0 + 1.5 -2x + x2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 -2x + x2 = 1.5 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 1.5 + 1 Reorder the terms: 1 + -2x + x2 = 1.5 + 1 Combine like terms: 1.5 + 1 = 2.5 1 + -2x + x2 = 2.5 Factor a perfect square on the left side: (x + -1)(x + -1) = 2.5 Calculate the square root of the right side: 1.58113883 Break this problem into two subproblems by setting (x + -1) equal to 1.58113883 and -1.58113883.
Subproblem 1
x + -1 = 1.58113883 Simplifying x + -1 = 1.58113883 Reorder the terms: -1 + x = 1.58113883 Solving -1 + x = 1.58113883 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 1.58113883 + 1 Combine like terms: -1 + 1 = 0 0 + x = 1.58113883 + 1 x = 1.58113883 + 1 Combine like terms: 1.58113883 + 1 = 2.58113883 x = 2.58113883 Simplifying x = 2.58113883
Subproblem 2
x + -1 = -1.58113883 Simplifying x + -1 = -1.58113883 Reorder the terms: -1 + x = -1.58113883 Solving -1 + x = -1.58113883 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -1.58113883 + 1 Combine like terms: -1 + 1 = 0 0 + x = -1.58113883 + 1 x = -1.58113883 + 1 Combine like terms: -1.58113883 + 1 = -0.58113883 x = -0.58113883 Simplifying x = -0.58113883
Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.58113883, -0.58113883}
