Question

Answer 1

`(4x+3)^2 - (4x-3)^2 -5x-2 =0`

`<=> (4x+3 - 4x+3)(4x+3+4x-3) -5x -2=0`

`<=> 3* 8x -5x -2 =0`

`<=> 24x-5x -2 =0`

`<=> 19x =2`

`<=>x =2/19`

`(x+5)^2 -16 =0`

`<=> (x+5)^2 = 16`

`<=> [(x+5=4),(x+5=-4):}`

`<=> [(x=-1),(x=-9):}`

`(x+2)^2 -9 =0`

`<=> (x+2)^2 =9`

`<=> [(x+2=3),(x+2=-3):}`

`<=> [(x=1),(x=-5):}`
