Question

Both roots of x^2 + Nx + 144 are equal to each other. Find all the possible values of N.

Answer 1

Answer:

N=+24,-24

Step-by-step explanation:

Well this is a quadratic equation and we can make further deductions using it's discriminant

b²-4ac=0

N²-4(1×144)=0

N²-576=0

N²=576

N=√576

N=+24,-24
