$\huge{\mathcal {\purple {A}\green {n}\pink {s}\blue {w}\purple{e}\green {r}}}$

The quadratic polynomial is y2+235y−5.

The quadratic polynomial is y2+235y−5.The zeros of the polynomial are:

  $y2+235y−5=0$

$⟹  y2+25y−25y−5=0$

$⟹  y(y+25)−25(y+25)=0$

$⟹  (y+25)(y−25)=0$

$⟹  y−25 and y=25=0$

The zeros are$−25 and 2$
