Question

Find a quadratic formula each with the given number as the sum and product of the zeroes a) 3 and 4 b) -2 and 3 C) -2 and 3 answer pls

Answer 1

Answer:

Step-by-step explanatiorn:

Let , alpha and beta are the roots

(a) so , a + B = 3 and aB = 4

So the required polynomial is,

P(x) = x square - ( a + B )x + (aB)

. = x square - 3x + 4.

( b) a +B = -2 and aB = 3

P(x) = x square - ( a+B )x + (aB).

= x square - (-2)x + 3 .

= x square + 2x + 3.

(c) same as (b) .
