Question

9x-x^2-20 Solve using splitting the middle term​

Answer 1

Answer:

-x^2 +9x -20 = 0

x^2 - 9x + 20 = 0

x^2 -5x - 4x + 20 = 0

x( x - 5) -4( x - 5) = 0

(x - 4)(x - 5) = 0

x = 4 or x = 5

Answer 2

Answer:

- x² + 9x - 20

- x² + 4x + 5x - 20

- x (x - 4) + 5 (x - 4)

(- x + 5) (x - 4)

Factors are -

x = 5

and

x = 4
