(4x + 5)(4x + 5)
40x+16=2540x=25-1640x=9x= 9/40x=0.225
(4x+5)(4x+5)
8(1+5x) +5 = 13+5x => 8+40x + 5 = 13 +5x => 13+40x = 13+5x => 13-13+40x = 13-13+5x => 40x = 5x => 40x - 5x = 0 => 35x = 0 => 35x/35 = 0/35 => x = 0

It is: (x2 + 5x) (x + 8)
x(x + 8)(x + 5)

The factorization of 25x2 + 40x + 16 is (5x+4)(5x+4).
4x+516x2 + 40x + 25= (4x + 5) (4x + 5)
40x+16=2540x=25-1640x=9x= 9/40x=0.225
A trinomial of the form ax2 + bx + c , where a is a square, c is a square and b = 2(sq root a)(sq root b). b can be a negative also. ex: x2 + 6x + 9 , note a = 1 or 16x2 - 40x + 25

8(1+5x) +5 = 13+5x => 8+40x + 5 = 13 +5x => 13+40x = 13+5x => 13-13+40x = 13-13+5x => 40x = 5x => 40x - 5x = 0 => 35x = 0 => 35x/35 = 0/35 => x = 0
35 + 40x + 5x2 = 5(7 + 8x + x2) = 5(7 + x)(1 + x)
It is an equation and the value of x is -3
