问题描述：
解方程：(4x+5)(4x-5)=4(2x+3)^2-(100x-17)
答
16x²-25=16x²+48x+36-100x+17
-25=48x+36-100x+17
52x=78
x=3/2
答

16x²-25=4（4x²+12x+9）-100x+17
16x²-25=16x²+48x+36-100x+17
52x=36+17+25
52x=78
x=1.5
答
（4X+5）（4X-5）=4（2X+3）平方-（100X-17）
16x^2-25=4(4x^2+12x+9)-100x+17
16x^2-25=16x^2+48x+36-100x+17
-25=-52x+53
52x=78
x=3/2
