Question

Form the equation whose roots are 1-3i , 1+3i

Answer 1

Answer:

for forming any quadratic equation given its roots use;

(x-a)(x-b)__(1)

where a and b are roots of that equation

Step-by-step explanation:

here,

keep a=1-3i and b=1+3i in equation (1)

you'll get

(x-(1-3i))(x-(1+3i))

(x-1+3i)(x-1-3i)

x^2-x-x3i-x+1+3i+x3i-3i-9i^2

x^2-2x+1+9_____(as we know square of iota is-1)

x^2-2x+10 answer
