Question

5a(2x-3y)²+2b(2x-3y)
plz answer in steps​

Answer 1

$\rm{5a(2x-3y)^2+2b(2x-3y)=5a(2x-3y)^2+2b(2x)-2b(3y)}$

$\longrightarrow\rm{5a(2x-3y)^2+2b(2x-3y)=5a(2x-3y)^2+4bx-6by}$

$\longrightarrow\rm{5a(2x-3y)^2+2b(2x-3y)=5a\left(4x^2-12xy+9y^2\right)+4bx-6by}$

$\longrightarrow\rm{5a(2x-3y)^2+2b(2x-3y)=20ax^2-60axy+45ay^2+4bx-6by}$

Answer 2

Answer:

20ax^2−60axy+45ay^2+4bx−6by

Step-by-step explanation:

Distribute:

=20ax^2+−60axy+45ay^2+(2b)(2x)+(2b)(−3y)

=20ax^2+−60axy+45ay^2+4bx+−6by

=20ax^2−60axy+45ay^2+4bx−6by
