Question

The sum and product of the zeroes of a quadratic polynomial
P(x) = ax
+ bx + c are - 3 and 2 respectively. Show that b+ c = 5a.
​

Answer 1

Heya

QUESTION SHOULD BE LIKE THIS

P( x ) = ax² + bx + c

then prove that a + b = -5a

rest same.

Sum of zeros in given quadratic polynomial is

-b/a = { -3 + 2 }

b/a = 1

b = a .... Equation ( i )

And

product of zeros is =

c/a = { -3 × 2 }

c/a = -6

c = -6a ... Equation ( ii )

Add Equation i and ii we get

b + c = a - 6a

b + c = -5a
