Question

find the zero of the quadratic polynomial 2x^2+5x-12 and verify relationship between zeroes and the coefficient​

Answer 1

Answer:

answer dear

Step-by-step explanation:

Find the zeros of the polynomial 2x2+5x-12 and verify the relationship between its zeros and coefficients. ... So, the zeros of f(x) are -4and32. Sum of the zeros = (-4+32)=-52=-(coefficient of x)(coefficient of x2), product of the zeros = (-4)×32=-122=constant term(coefficient of x2).

Answer 2

Step-by-step explanation:

2x²+5x-12=0

2x²+8x-3x-12=0

2x(X+4)-3(X+4)=0

(X+4)(2x-3)=0

X=-4,3/2

sum of the roots =-4+3/2=-5/2

=-b/a

product of the roots=-4×3/2=-6

=C/a
