Question

if 1 is the zeros of the quadratic polynomial ax^2 + bx + c, a not equal to 0, find the value of (b+c)/a
​

Answer 1

Answer:

-1

Step-by-step explanation:

the zero of the polynomial is 1

p(x) = ax² + bx + c

p(1) = a x 1² + b x 1 +c

  0 = a + b +c

now b + c = -a

now we can find the value of the b+c / a

= b+c / a

= -a / a (∵ b+c = -a)

= -1
