a) x2-5x-24=0

Answer 1

X=either -3 or 8

Explanation:

Assuming that you've written X² then

  x²-5x-24=00

 product(p)=-24 (you find two numbers which when you multiply their product is (-24) and their sum(-5)

sum(s)=-5 (-8,3)

  (x²-8x)+(3x-24)=0

 x(x-8)+3(x-8)=0

 (x+3)(x-8)=0

 x+3=0 x-8=0

 x=-3 x=

Answer 2

2 - 5x - 24 = 0 (calculate)

-22 - 5x = 0 (move the constant to the right)

-5x = 22 (divide both sides)

x = -22/5
