Answer:
The require value for s is 24.
Step-by-step explanation:
We are given that the expression x² + sx + 144 and we have to make it a square of a binomial.
Hence, we have to find the value of s for this purpose.
Now, let us assume that (x + 12)² = x² + sx + 144
⇒ x² + 24x + 144 = x² + sx + 144
⇒ 24x = sx
⇒ s = 24
Therefore, the require value for s is 24. (Answer)
