Question

10. What should be added to (x-4) (x + 6) to get
the product (x - 3)(x - 8) ?​

Answer 1

Answer:

-13x+48

Step-by-step:

(x-4)(x+6) = x^{2} +6x -4x -24

               = x^{2} +2x -24  

let 'k' be added to this

x^{2} +2x -24 +k = (x-3)(x-8)

x^{2} +2x -24 +k = x^{2} -11x + 24

2x - 48 +k = -11x

-48 +k = -13x

k = -13x+48

tell me what i did wrong, if it is wrong.
