you can get a quadratic in A or B
The second part of the question is: Which of the following quadratics has A and B as its root? 1)x^2+2x+5=0. 2) x^2-5x+2=0. 3)x^2-4x+25=0. 4)x^2+4x+25=0. 5) x^2-25x-4=0
AB = 25 A+B = 4
you found A,B ?
quadratic : \(x^2 - (sum)x + product =0\) \(x^2 - (A+B)x + AB =0\)
