Factorization of a ^ 4-14a ^ 2B ^ 3 + 49b ^ 6
（a^2-7b^3）^2
Factorization: (A-3) (x-4) - (x ^ 2-4)
Wrong number. It's x-3
It's x-3, right
Original formula = x & # 178; - 7x + 12-x & # 178; + 4
=-7x+16
(x2-3) (x2-2) - 2 cross multiplication (x2 + 3x + 2) (x2 + 7x + 12) - 24 cross multiplication
①(x^2-3)(x^2-2)-2=x^4-5x^2+4=(x^2-1)(x^2-4)=(x+1)(x-1)(x+2)(x-2)②(x^2+3x+2)(x^2+7x+12)-24=x^4+7x^3+12x^2+3x^3+21x^2+36x++2x^2+14x+24-24=x^4+10x^3+35x^2+50x=x(x^3+10x^2+35x+50)=x[(x^3+10x^2+25x)+(10x...
