Question

Which equation is true for x = –6 and x = 2?

A.) 2x2 – 16x + 12 = 0
B.) 2x2 + 8x – 24 = 0
C.) 3x2 – 4x – 12 = 0
D.) 3x2 + 12x + 36 = 0
plsssss help its a timed question

Answer 1

B.) 2x2 + 8x – 24 = 0

Explanation:

For x= 2 and x= -6

Let's determine the equation of the solutions.

(X-2)(x+6)=0

X²+6x -2x -12= 0

X² +4x -12= 0

So the above is the real equation to the solution of x= 2 and x= -6

But in the options, we don't have something like that.

But let's try and multiply the solution will a positive or negative integer.

Lets start with +2

2(X² +4x -12= 0)

2x² + 8x -24 = 0

Yeah, option B is the answer
