Question

Find a polynomial equation in the standard form whose roots:1,2,and -3.

Answer 1

Step-by-step explanation:

sum of roots =1+2-3=0

sum of products of two roots = 1x2+ 2× -3+ -3×1=2-6-3 = -7

product of roots= 1×2× -3 = -6

polynomial=

${x}^{3} - 0 \times {x}^{2} + ( - 7)x - ( - 6)$

${x}^{3} - 7x + 6$
