Question

x^2 + 6x+8=0
(2+4=6
2*4=6)
What will be the next step and ow to split can someone tell with written instructions. (typed)

Answer 1

x² + 6x + 8 = 0

Now,

2+4 = 6

2×4 = 8

Step - 1 --> Split the middle term such that Product of their number is 8x²(2x×4x) and sum of their number is 6x(2x+4x).

So, number are 2x+4x.

Step - 2 --> Now put this number in the middle term.

Now, equation becomes

x² + 2x + 4x + 8 = 0

Step - 3 --> Now, you Common out the number

x(x+2) +4 (x+2) = 0

(x+2) (x+4) = 0

Step - 4 --> Last step , Now put this common factor = 0.

(x+4) = 0 and (x+2) = 0

x = - 4, -2

This is your Answer ; x = -4,-2

Answer 2

Answer:

x=-4,-2
