Question

If x2 + 10x + λ is a perfect square, then the possible value of λ is​

Answer 1

Answer:

possible value of λ is is 5

Step-by-step explanation:

x²+10x+λ is in form of (a+b)²= a²+2ab+b²

here a=1, find b, the possible value of b is 5.

10can be written in the form of 2ab = 2*1*5

x²+(2*5*1)x+5²

λ=5 ,λ²=25

x2 + 10x + λ = (x+5)² =(x+λ )²

a²+2ab+b² compare the given equation with this
