Question

phân tích đa thức thành nhân tử  y^2-12y+36-144x^2

Answer 1

\(y^2-12y+36-144x^2=\left(y-6\right)^2-\left(12x\right)^2=\left(y-12x-6\right)\left(y+12x-6\right)\)

Answer 2

\(=\left(y^2-12y+36\right)-144x^2=\left(y-6\right)^2-144x^2=\left(y-12x-6\right)\left(y+12x-6\right)\)

Answer 3

\(( y − 12 x − 6 ) ( y + 12 x − 6 )\)

Answer 4

y2−12y+36−144x2=(y−6)2−(12x)2=(y−12x−6)(y+12x−6)
