What is the following product? Will award brainliest! (4x startroot 5x^2 endroot +2x^2 startroot 6 endroot)^2

Last option is correct

104x^4 + 16x^4√30

Step-by-step explanation:

let’s simplify what we have in the roots;

4x √(5x^2) = 4x^2 √5

(4x^2√5) + 2x^2 √(6)^2

(4x^2√5)(4x^2√5) + 4x^2√5(2x^2√6) + 2x^2√6(4x^2√5) + 2x^2√6(2x^2√6)

= (16 * x^4 * 5) + (8 * x^4 * √30) + (8 * x^4 * √30) + (4 * x^4 *6)

= 80x^4 + 8x^4 √30 + 8x^4 √30 + 24x^4

= 104x^4 + 16x^4√30

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
