3p + 4p +10 = 5p + 2 Subtracting 5p from both sides: 3p + 4p - 5p + 10 = 5p + 2 - 5p ie 2p + 10 = 2 Subtract 10 from both sides: 2p + 10 - 10 = 2 - 10 ie 2p = -8 Divide both sides by 2: p = -4
Well, gee, I don't know.Let's work it out:4p - 2 = 3pAdd 2 to each side of the equation:4p = 3p + 2Subtract 3p from each side:p = 2
9p - 5
2(2p + 5q)
p2 - 8p = 0 The square would be (8/2)2 = 42 = 16 So, p2 - 8p + 16 = 16 then (p - 4)2 = 42 So that (p - 4) = +/- 4 then p = 4 +/- 4 ie p = 8 or p = 0 With this particular question, factorisation is so much easier: p2 - 8p = 0 p(p - 8) = 0 So p = 0 or p = 8 Done!
