Question

Verify -3, -4 are zeros of the polynomial P(x) =x2+7x+12

Answer 1

Step-by-step explanation:

The polynomial is

x²+7x+12a=1,b=7,

c=12Factors of x²+7x+12=x²+4x+3x+12=x(x+4)+3(x+4)=(x+4)(x+3)Zeroes of the polynomialx²+7x+12 =0(x+4)(x+3)=0x= -4,-3ZEROES = -4, -3SUM OF ROOTS = -4-3=-b/a=-7/1=> -7=-7PRODUCT OF ROOTS= -4*-3=c/a=> 12=12
