Question

BY HIT AND TRAIL METHOD
.......do this please
i am confused
= 2x3 -3x2-17x+30​

Answer 1

Answer:

X=. -1.7

Step-by-step explanation:

2×3=6

-3×2=-6

• 2×3-3×2-17x+30
• 6-6-17x+30
• 0-17x+30

The use of Hit and trial method starting from grade 7 . This method is used to find the factors or roots of the any polynomial of degree more than two.In this method generally we try to put some different-different value in the given polynomial until the polynomial satisfies to zero of that polynomial.

• now equate the equation with 0
• 0-17x+30=0
• -17x=0+30
• -17x=30
• X=30/-17
• X=-30/17
• x=. -1.7

So,it is not a zero of a polynomial
