if a+b= 6 and ab = 5, find the value of a²+b²
Answers
Answer:
kindly mark my answer as brainliest
Step-by-step explanation:
given : a+b=6 and ab= 5
(a+b)² / a²+b²=a²+2ab+b²
=a²+b²+2×5
=(6)²+10
=36+10
=46
Therefore a²+b²=46
Answer:
Originally Answered: A+B=5 and ab =6, what is the value of a²-b²? If a + b = 5 then b = 5-a. therefore if ab = 6, then.

a + b = 5. b = 6/a; therefore a + 6/a = 5; therefore a² - 5a + 6 = 0 So we have a quadratic ... More
