Question

Represent the zeroes of the quadratic polynomial 3x2

-x - 4 graphically​

Answer 1

Answer:

Zeroes of the given polynomial are- -1 and $\frac{4}{3}$

Step-by-step explanation-

Put the polynomial equal to zero as zeroes of a polynomial are those real number which can make its value zero

$3x^{2} -x-4$=0

$3x^{2} -(4-3)x-4=0\\3x^{2} -4x+3x-4=0\\(3x^{2} -4x)+(3x-4)=0\\\\x(3x-4)+1(3x-4)=0\\\\(x+1)(3x-4)=0\\Now ,Put\\x+1=0\\x=-1\\3x-4=0\\x=4/3$
