Mathematics

a = -3 and b = 8

Step-by-step explanation:

change it into x² + 5x - 24 = 0

then think two number which:

if we add both off them the result will be +5 and

if we multiply them, the result is -24

so i came with +8 and -3

then the quadratic equation can change form into

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

so a = -3 and b is 8
