Question

19] Find the zeroes of the polynomial P (x) = 4m2 - m - 3.​

Answer 1

Answer:

Step-by-step explanation:

p(x)=4m²-m-3

     =4m²-4m+3m-3

     =4m(m-1)+3(m-1)

     =(4m+3)(m-1)

     m=+1 , -3/4

sorry if any mistake

Answer 2

Given :

P (x) = $4\times m^{2} -m-3$

To Find:

find the zeroes of the polynomial

Step-by-step explanation:

• The zeroes of this polynomial can be found by factorize the polynomial and for this first step should be to find the product of first and last term and then write the second term from the product of the first and first step .This is the basic step of the factorization.
• $P(x)=4m^{2} -m-3\\=4m^{2} -4m+3m-3\\=4m(m-1)+3(m-1)\\=(4m+3)(m-1)$
• Here in this equation roots can be found by equating both these factors as equal separately  to zero.
• $4m+3=0\\4m=-3\\m=-3\div 4\\and \\m-1=0\\m=1$
• The roots of m are $1$ and $-3\div 4$

The zeroes of polynomial are $1$ and ($-3\div 4$)
