Question

Select the polynomial that is a perfect square trinomial.

9x2 + 9x + 1

36b2 − 24b + 8

16x2 + 24x + 9

4a2 − 10a + 25

Answer 1

Hello,

Answer C

16x²+24x+9=(4x+3)²

Answer 2

Answer: (c)  $16x^{2}+24x+9$.

Step-by-step explanation:

(a) $9x^{2} +9x+1$ cannot be further factorised, so this is not correct option.

(b) $36b^{2}-24b+8$ also cannot be expressed as factors, and hence this is too not correct.

(c) $16x^{2}+24x+9=({4x+3} )^2$, the correct one.

(d) $4a^{2}-10a+25$ cannot be factorised, so its not correct.

Thus, (c) $16x^{2}+24x+9$ is the correct option.
