1 (a - 6)(a+6)
2 (3x - 1)²
3 (5z + 1)²
4 (x²-1)(x+1) = (x-1)(x+1)(x+1)
5 (27y³ + 64) =
2 (3x - 1)²
3 (5z + 1)²
4 (x²-1)(x+1) = (x-1)(x+1)(x+1)
5 (27y³ + 64) =
1.
a² - 36 = (a-6)(a+6)
2.
9x²-6x+1 = (3x - 1)²
3.
1+10z+25z² = 25z² + 10z +1 = (5z +1)²
4.
x³ - 1 = (x - 1)(x² + x + 1)
5.
27y³+64 = (3y + 4)( 9y² - 12y + 16)
a² - 36 = (a-6)(a+6)
2.
9x²-6x+1 = (3x - 1)²
3.
1+10z+25z² = 25z² + 10z +1 = (5z +1)²
4.
x³ - 1 = (x - 1)(x² + x + 1)
5.
27y³+64 = (3y + 4)( 9y² - 12y + 16)
