x-4=\u00b1(5-2x)
x-4=5-2x.x=3
x-4=-(5-2x)=2x-5,x=1

(x-4)²-(5-2x)²=0
(x-4+5-2x)(x-4-5+2x)=0
(1-x)(3x-9)=0
x=1,x=3
17.原式=3[x － (1+√7)/3][x － (1-√7)/3]
18.原式=(p－25)(p＋4)
19.原式=(3x＋2)(4x－1)
20.原式=(2p＋9)(3p－4)
21.原式=(m＋5)(m＋12)
22.原式=[(a^2－a)－2][(a^2－a)－6]=(a＋1)(a－2)(a＋2)(a－3)
23.原式=[2(m＋3n)－5][3(m＋3n)＋2]=(2m＋6n－5)(3m＋9n＋2)
24.原式=(x^3－x^2y)＋(xy^2－y^3)=(x^2)(x－y)＋(y^2)(x－y)=(x－y)(x^2＋y^2)
25.原式=(2a－b)(a＋b)－(2a－b)=(2a－b)(a＋b－1)
