If x^3+ax^2-18x+b = (x+5)(x-4)(x+2) what is a and b

blondinia [14]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$(x + 5)(x - 4)(x + 2) =$

$(x + 5) ({x}^{2} - 2x - 8) =$

${x}^{3} - 2 {x}^{2} - 8x + 5 {x}^{2} - 10x - 40 = \\$

${x}^{3} + 3 {x}^{2} - 18x - 40$

_________________________________

Compare :

${x}^{3} + 3 {x}^{2} - 18x - 40$

${x}^{3} + a {x}^{2} - 18x + b$

Thus :

$a = 3$

and

$b = - 40$
