Question

plz answer fast find the zeros of quadratic polynomial 8 x square - 21 - 22 x and verify the relationship between zero and the coffee sent

Answer 1

P(x)=8x^2-22x-21 sum of zero=alpha+beta =-(d)/a where d is cofficient of x and a is cofficient of x^2 so alpha+ beta=22/8 similerly product of zero alpha ×beta =c/a where c is constant and a is cofficient of x^2then alpha×beta=-21/8 .similerly split middle term of p(x) hence you will get the zero by splitting the middle term .hence the relation between zero are proved
