Question

factorizesion of x square - 3x -40
​

Answer 1

Answer:

x=8,-5

Step-by-step explanation:

x^2-3x-40

x^2-8x+5x-40=0

x(x-8)+5(x-8)=0

(x+5)(x-8)=0

x=8,-5

Answer 2

Step-by-step explanation:

x² -8x +5x -40

x(x -8) +5(x -8)

(x -8)(x +5)

So, if x-8=0 then x= 8

and if x+5=0 then x= -5
