Question

The equation whose roots are –2 and 3 is:

A.

x2x+6=0x^2-x+6=0​​

B.

x2x6=0x^2-x-6=0​​

C.

x25x+6=0x^2-5x+6=0​​

D.

x2+3x6=0x^2+3x-6=0​​

Correct option is B

Given:

Roots of the equation are −2 and 3.

Concept Used:
For a quadratic equation, if the roots are r1r_1​ and r2r_2​, the equation can be written as:

(xr1)(xr2)=0(x - r_1)(x - r_2) = 0​​

Solution:
The roots are r1=2 r_1 = -2​ and r2=3r_2 = 3​. The equation becomes:

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

Now, expand the equation:

x23x+2x6=0x^2 - 3x + 2x - 6 = 0​​

x2x6=0x^2 - x - 6 = 0​​

The equation is x2x6=0.x^2 - x - 6 = 0.​​
