Answer 1

Explicación paso a paso:

a. x² -18x+ 81 = 0. ( x - 9 ). (x -9 ) = 0

b. x²+32x+256= 0 (x + 16 ) (x + 16 ) = 0

c. x²+x+1/4 = 0. ( x + 1/2) (x+1/2)= 0

d. x² +2x-8= 0. (x + 4 ) ( x - 2)= 0

e. x²+7x+12 = 0. ( x + 4) (x + 3)

f. x²-6x-16 = 0 (x-8)(x+2)

g. x²-40+400= 0 ( x - 20)(x-20)

h. x²-2x-15 = 0. (x-5)(x+3)

i. x²-10x +9= 0 (x -3)(x-3)-4x = 0
