Question

find the equation whose roots are - 2/5 and 3/4​

Answer 1

Answer:

The required equation

is x2 – 3xx + i = 0

Step-by-step explanation:

Step-by-step explanation:

We are given that the roots are -2/3

and 4/5

So(x+) = 0 and (x – 4) = 0 are

the roots

So, (x +(3)(x – $) = 0

2(2+())+(-3)(x+)=0

x2 – 3x – x + = 0

22 – 8 + = 0

=

Hence The required equation is x2

1 x + 1 = 0
