Question

If (3p-2q)=5, pq=4, find (3p+2q).​

Answer 1

Answer:

Step-by-step explanation:

Given:-

(3p-2q)=5

pq=4

3p+2q=?

let a=3p

and b=2q

we know that:-

(a+b)²-(a-b)²=4ab

(3p+2q)^2-(3p-2q)^2=4pq

(3p+2q)^2-(5)^2=4×4×3×2

(3p+2q)^2=16×6

(3p+2q)^2=96+25

3p+2q=121

3p+2q=under root 121

thats

+11

or -11
