Step-by-step explanation: 2x²-3x-4=0 Consider alpha as ‘A’ and beta as ‘B’. A+B = -b/a = 3/2 AB = c/a = -4/2 = -2 (A+B)²=A²+B²+2AB (3/2)²=A²+B²+2×(-2) 9/4=A²+B²-4 9/4-4=A²+B² A²+B²=(9-16)/4 = -7/4 Reply
Step-by-step explanation:
2x²-3x-4=0
Consider alpha as ‘A’ and beta as ‘B’.
A+B = -b/a = 3/2
AB = c/a = -4/2 = -2
(A+B)²=A²+B²+2AB
(3/2)²=A²+B²+2×(-2)
9/4=A²+B²-4
9/4-4=A²+B²
A²+B²=(9-16)/4 = -7/4
