1.	(I) If x2+x−a=0 has integral roots(P)2and a∈N,then a can be equal to(II) If the equation ax2+2bx+4c=16(Q)12has no real roots and a+c>b+4,then the integral value of c can be(III) If equation x2+2bx+9b−14=0(R)1has only negative roots, then the integralvalues of b can be(IV) If N be the number of solutions of(S)30the equation \|x−\|4−x\|\|−2x=4, thenthe value of N is Which of the following is the only CORRECT combination?
Answer» $\begin{matrix} (I) If x^{2} + x - a = 0 has integral roots & (P) 2 and a \in N, then a can be equal to (II) If the equation a x^{2} + 2 b x + 4 c = 16 & (Q) 12 has no real roots and a + c > b + 4, then the integral value of c can be (III) If equation x^{2} + 2 b x + 9 b - 14 = 0 & (R) 1 has only negative roots, then the integral values of b can be (IV) If N be the number of solutions of & (S) 30 the equation \| x - \| 4 - x \| \| - 2 x = 4, then the value of N is \end{matrix}$ Which of the following is the only CORRECT combination?
