Question

Find a quadratic polynomial the sum and product of whose zeroes are 1and-12 respectively.Henca find the zeroes

Answer 1

Step-by-step explanation:

Sum = 1+ (-12)

S= 11

P= 1x-12

P = - 12

Quadratic poly. = (x) 2 +sx - p = 0

( x) 2 + 11x - ( - 12)

(x) 2 +11x + 12

( x) 2 + 11x +12 = 0

(x) 2 +12x - 1x +12=0

X(x + 12)- 1(x + 12)=0

X=12
