Question

5. find the roots of the equations
a) x²-3x+2=0

​

Answer 1

Answer:

Step-by-step explanation:

See now, We have to find such a multiple whose Multiplication is 2 and sum is -3 and such multiples are -2 &-1 so our equation will be

x^2-2x-x+2

x(x-2)-1(x-2). (-×-=+)

we then get that

(x-1)(x-2)=0

so if x-1=0 then, x=1

and is x-2 =0 then x=2

so the roots are 1&2.

I hope you got the answer.
