Question

23 10. Construct a quadratic equation whose roots are 1 and 2.A 3X-3x + 2-0 B. 3 + 3x - 2-0 C 22 + 3x - 2.0 D 2 - 3x +2=0 E.2x - 3x - 2 =0​

Answer 1

Explanation:

Basic quadratic equation has this following form:

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

where x1 and x2 are the roots.

For
`x_(1)=1` and
`x_(2)=2`, we can find:

`(x-1)(x-2)=0 \rightarrow x^(2)-2x-x+2=0 \rightarrow x^(2)-3x+2=0`
