On the polynomial a of X to the second power, the third power of X + the second power of 2x - the third power of 4x + the second power of 2x ax - 9, a quadratic trinomial is obtained by combining the similar terms Value of

On the polynomial a of X to the second power, the third power of X + the second power of 2x - the third power of 4x + the second power of 2x ax - 9, a quadratic trinomial is obtained by combining the similar terms Value of

a^2x^3+2x^2-4x^3+2x-ax^2-9
=(a^2-4)x^3+(2-a)x^2+2x-9
A ^ 2-4 = 0,2-a is not equal to 0,
So, a = - 2

The common factor should be extracted from the factorization of polynomial 12x ^ 3Y ^ 2-8x ^ 2Y ^ 3 + 6x ^ 2Y ^ 2

12x^3y^2-8x^2y^3+6x^2y^2= 2x^2y^2(6x-4y+3)

Factorization of polynomial 2x ^ 2-1 / 2Y ^ 2

2x^2-1/2Y^2
=1/2（4x^2-y^2)
=1/2(2x+y)(2x-y)

When factoring the polynomial - 6 ^ 3Y ^ 2 + 3x ^ 2Y ^ 3, the common factor should be extracted

Is - 6x & # 179; Y & # 178; + 3x & # 178; Y & # 179;
=3x²y²(y-2x)
