Question

find the zeros of quadratic polynomial x2+x-12, and verify the rationalship between the zero and its coefficient​

Answer 1

Answer:

Zeros of Polynomial :

x = (-4) OR x = 3

Step-by-step explanation:

= x² + x - 12

= (x² + 4)(-3x - 12)

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

= (x + 4)(x - 3)

Such that,

x = (-4) OR x = 3

Verification :

Sum of Zeros = -b/a = -1/1 = (-1)

α + ß = -4 + 3 = (-1)

Product of Zeros = c/a = -12/1 = (-12)

αß = (-4)3 = (-12)
