Question

Q1 A Choose and write the correct alternative.
(1) The sum of the roots of one of the following equations is 3. Wh
one is the equation ?
(A) x? - 3x + 2 = 0
(B) x + 3x + 2 = 0
(C) 3x2 + 6x + 10 = 0 (D) x + 3x - 2 = 0​

Answer 1

Answer:

The answer is A) x^2-3x+2

Step-by-step explanation:

as x^2-sx+p

where s= sum of zeros

Answer 2

Answer:

(A) $x^{2} - 3x + 2$

Step-by-step explanation:

Let α and β be two roots of the required equation.

then ⇒ α + β = $\frac{-b}{a}$

For option (A); a = 1 , b = -3

⇒ α + β = $\frac{-(-3)}{1}$ = 3

Which is the required sum, hence option (A) is correct. (also in your question option A is written slightly wrong, it should be $x^{2}$ instead of x?).

Hope it helps
