Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

( 5x⁴ + 3)²

( 5x⁴ + 3)(5x⁴ + 3)

<u>Expand</u><u> </u><u>using</u><u> </u><u>FOIL</u>

That's

(5x⁴)(5x⁴) + 5x⁴(3) + 3(5x⁴) + 3(3)

We have

<h3> $25 {x}^{8} + {15x}^{4} + {15x}^{4} + 9$ </h3>

<u>Add and simplify like terms</u>

We have the final answer as

<h2> ${25x}^{8} + {30x}^{4} + 9$ </h2>

Hope this helps you
