Question

(3x + 4y - 5p)^2 expand it ​

Answer 1

Answer:

Actually it is of the form of (a+b-c) ^2= a^2+b^2+c^2+2ab-2bc-2ca.

so, according to the problem

(3x+4y-5p)^2 = (3x) ^2+(4y) ^2+(5p) ^2+2(3x)(4y) -2(4y)(5p) -2(5p)(3x)

= 9x^2+16y^2+25p^2+24xy-40yp-30px

Answer 2

9x2+16y2+25p2+24xy-40yp-30px
