Question

add the expression 5p+2q-7r+3, 2r-4p-8, 11q - 8p + 3r -1 and 3q-2r+5​

Answer 1

Step-by-step explanation:

Given: 6p+4q−r+3,2r−5p−6,11q−7p+2r−1 and 2q−3r+4

To add the given terms we have to add coefficient of like terms:

∴(6p+4q−r+)3+(2r−5p−6)+(11q−7p+2r−1)+(2q−3r+4)

=(6−5−7+0)p+(4+0+11+2)q+(−1+2+2−3)r+(3−6−1+4)

=−6p+17q+0r+0

=17q−6p
