Question

Factorise x^3+19x-150

Answer 1

here is your answer pls reply if helpful

Answer 2

PLEASE MARK IT AS BRAINLIEST Factoring  x2-19x-150 

The first term is,  x2  its coefficient is  1 .
The middle term is,  -19x  its coefficient is  -19 .
The last term, "the constant", is  -150 

Multiply the coefficient of the first term by the constant   1 • -150 = -150 

Find two factors of  -150  whose sum equals the coefficient of the middle term, which is   -19 .
Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -25  and  6 
                     x2 - 25x + 6x - 150
Add up the first 2 terms, pulling out like factors :
                    x • (x-25)
              Add up the last 2 terms, pulling out common factors :
                    6 • (x-25)
Add up the four terms of step 4 :
                    (x+6)  •  (x-25)
          
(x + 6) • (x - 25)
