Question

Dind the zeroes of polynomial 3xsquare+15x+12

Answer 1

Answer:

-1..............is the answer......

Answer 2

Step-by-step explanation:

3x^2+15x+12=0

3x^2+(12+3)x+12

3x^2+12x+3x+12

3x(x+4)+3(x+4)

(x+4)(3x+3)

either

x+4=0 3x+3= 0

x=-4 3(x+1)=0

x+1=0

x=-1

hence -4 and -1 are the zero of the polynomial
