solve by completing the square method-
1.6m2 +m=2
2.4p2 +7=12p
Dear Student!!
(1) 6m2 + m = 2
dividing throughout by 6
Hence, roots of the equation are .
(2) 4p2 + 7 = 12p
⇒ 4p2 – 12p + 7 = 0
⇒ (2p)2 – 2(2p)3 + (3)2 – (3)2 + 7 = 0 (adding & subtracting (3)2)
⇒ (2p –3)2 – 9 + 7 = 0
⇒ (2p –3)2 = 2
Thus, roots of the equation are .
