For what values of x is x^2 + 2x = 24 true?

maw [93]

Answer:

$x = -6, x = 4$

Step-by-step explanation:

Step 1: Factor

Subtract 24 from both sides

$x^2 + 2x- 24 = 24 - 24$

$x^2 + 2x - 24 = 0$

Make two different x's

$x^2 + 2x - 24 = 0$

$x^2 + 6x - 4x - 24 = 0$

Make two different parenthesis

$x^2 + 6x - 4x - 24 = 0$

$(x + 6)(x - 4) = 0$

Step 2: Solve for x in both equations

$x + 6 = 0$

$x + 6 - 6 = 0- 6$

$x = -6$

$x - 4 = 0$

$x - 4 + 4 = 0 + 4$

$x = 4$

Answer: $x = -6, x = 4$

Answer:

None of them.

Step-by-step explanation:

Each and every straight line is of one kind in terms of its pattern: it can be presented in the view of $y = kx + b$ : $k$ is the slope or gradient of the line, $b$ is the y-intercept of the line. I will not let the cat out of the bag if I say that any parallel lines do not intersect one another, hence they should have the same value of coefficient $k$ .
