Best answer

दिया गया समीकरण

22x+4-4 – 8·2x+2+1 = 0

22x+4 · 24 – 8·2x+2 + 1 = 0

16·22(x+2) – 8·2x+2 + 1 = 0

माना 2x+2 = y

∴ दिया गया समीकरण

16yx – 8y + 1 = 0

16yx – 4y – 4y + 1 = 0

4y(4y – 1) – 1(4y – 1) = 0

(4y – 1)(4y – 1) = 0

दोनों पक्षों में घातों की तुलना करने पर

x + 2 = – 2

x = – 2 – 2

x = – 4
