Answer 1

9x^2-4=3х-2)(3х+2)

4a^2-25=(2а-5)(2а+5)

16-49y^2=(4-7у)(4+7у)

9a^2-4b^2=(3а-2b)(3а+2b)

16m^2-9n^2=(4m-3n)(4m+3n)

25x^2-y^2=(5x-y)(5x+y)

4x^2-1=(2x-1)(2x+1)

1-36a^2=(1-6a)(1+6a)

_______________________________

x^2y^2-z^2=(x-y-z)(x+y+z)

a^2b^2-16=(a-b-4)(a+b+4)

9-m^2n^2=(3-m-n)(3+m+n)

b^2c^2-1=(b-c-1)(b+c+1)

y^4-x^2=(y^2-x)(y^2+x)

y^6-9=(y^3-3)(y^2+3)

x^10-25=(y^5-5)(y^2+5)

9-b^4=(3-b^2)(3+b^2)

_________________________

(1+3m)(1-3m)=1-9m^2

(2x-1)(2x+1)=4x^2-1

(a-3b)(3b+a)=a^2-9b^2

(4x+3y)(3y-4x)=16x^2-9y^2

(5b-10c)(5b+10c)=25b^2-100c^2

 

 

 

Answer 2

Разложите на множители a^2-b^2=(a-b)(a+b)

9x^2-4=(3х-2)(3х+2)

4a^2-25=(2а-5)(2а+5)

16-49y^2=(4-7у)(4+7у)

9a^2-4b^2=(3а-2b)(3a+2b)

16m^2-9n^2=(4m-3n)(4m+3n)

25x^2-y^2=(5x-y)(5x+y)

4x^2-1=(2x-1)(2x+1)

1-36a^2=(1-6a)(1+6a)

Разложите на множители

x^2y^2-z^2=(xy-z)(xy+z)

a^2b^2-16=(ab-4)(ab+4)

9-m^2n^2=(3-mn)(3+mn)

b^2c^2-1=(bc-1)(bc+1)

y^4-x^2=(y^2-x)(y^2+x)

y^6-9=(y^3-3)(y^3+3)

x^10-25=(x^5-5)(x^5+5)

9-b^4=(3-b^2)(3+b^2)

Выполните умножение

(1+3m)(1-3m)=1-3m+3m-9m^2=1-9m^2

(2x-1)(2x+1)=4x^2+2x-2x-1=4x^2-1

(2x-y)(2x+y)=4x^2+2xy-2xy-y^2=4x^2-y^2

(a-3b)(3b+a)=3ab+a^2-9b^2-3ab=a^2-9b^2

(4x+3y)(3y-4x)=12xy-16x^2+9y^2-12xy=9y^2-16x^2

(5b-10c)(5b+10c)=25b^2+50bc-50bc-100c^2=25b^2-100c^2
