Question

For how many integer values of x, the value of (x-3)(-2-x) is NOT NEGATIVE?

Answer 1

Lets Solve

(x-3)(-2-x)

x(-2-x)-2(x-3)

-2x^2 -x^2-2x+6

-3x^2-2x+6

3x^2+2x-6=0

Take Discriminant =0

D=b^2-4ac

0= (2)^2-4×3×-6

0=4+72

0=76

76 is answer

Answer 2

Answer:

Answer is 76.

Step-by-step explanation:

x-3(-2-x)

x(-2-x)-2(x-3)

-2x^2-x^2-2x+6

-3x^2-2x+6

3x^2+2x-6=0

Discriminant=0

D=b^2-4ac

0=(2)^2-4^3^-6

0=4+72

0=76 ans
