Question

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

2x2 – 16x + 12 = 0
2x2 + 8x – 24 = 0
3x2 – 4x – 12 = 0
3x2 + 12x + 36 = 0

Answer 1

Answer:

2nd equation

put the values of x in it

2×(-6)^2+8×(-6)-24

72-48-24

72-72=0

which is our required answer

Answer 2

Answer:

option B

2x2+8x-24=0

Step-by-step explanation:

2x2+8x-24

put x=-6

2(-6)*(-6) +(8*(-6)-24

=2*36-48-24

=72-72=0

put x=2

2(2*2)+16-24

=2*4+16-24

=8+16-24

=24-24

=0
