Quadratic equation. Find the value of m so that the roots of the equation (4 - m) x^2 + (2m + 4)x + (8m + 1) = 0 may be equal.
nikitadnepr [17]

The quadratic has one root with multiplicity 2 if the discriminant is 0, which is

(2m+4)^2-4(4-m)(8m+1)

(That is, for a quadratic ax^2+bx+c, the discriminant is b^2-4ac.)

Set the discriminant equal to 0 and solve for m:

(2m+4)^2-4(4-m)(8m+1)=0

4m^2+16m+16+32m^2-124m-16=0

36m^2-108=0

36m(m-3)=0

\implies m=0\text{ or }m=3
