WebThe discriminant of the quadratic equation x 2 − ( 5 − k) x + ( k + 2) = 0 is Δ = k 2 − 14 k + 17. We want Δ to be always positive, then the given equation will always have two distinct real roots. For this to happen, the discriminant of Δ must be negative. But, the discriminant of Δ is Δ ′ = ( − 14) 2 − 4.17 = 128 > 0 is positive. WebDetermine all real values of a.A2 = 81. A. a = 9 B. a = ±9 C. a = 40.5 D. a = ±40.5. Answer by Guest.

Web10 years ago. To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment. WebReal number calculator.
