Question

Construct the quadratic equation whose roots are given below -
(i) 3, - 3
(ii)3+√3,3-√3​

Answer 1

Answer:

(i) $x^{2}$-9

Step-by-step explanation:

since solution set is {3,-3}

roots are 3 and  -3

x=3 and x= -3

x-3 =0 or x+3=0

(x-3)(x+3)              according to the zero product rule

$x^{2} -3^{2}$                              as (a+b) (a-b) = $a^{2} - b^{2}$

therefore the answer is  $x^{2} -$9
