Question

Find all the zeroes of the polynomial x3+4x2+x-6, if one of its zeroes is -3.

Answer 1

Step-by-step explanation:

• Take a equation with given zero of polynomial ie x= -3, => x+3 = 0
• divide it with the above equation
• tou will get a double degree equation
• find zeroes according to factorization method
• do verification with every zero of the polynomial with the given equation to ensure that answer is correct
• You will get zero (0) when you substitute any one of the zero
• Or you can even multiply them in this way
• if a,b,c are three zeroes of f(x) then
• (x-a)(x-b)(x-c)=f(x)
• if any zero of polynomial is negative you have to change from - to +

Hope you understand my explanation

Answer 2

zeros are -2,1and3. see in photo. ok
