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

Answer:

Step-by-step 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:

$(x-1)(x-2)=0 \rightarrow x^{2}-2x-x+2=0 \rightarrow x^{2}-3x+2=0$
