Answer:
The correct answer is option B). 7x² -12x√14 + 72
Step-by-step explanation:
I<u>dentity</u>
(a - b)² = a² - 2ab + b²
Find the product
It is given that ( x√7 - 3√8)(x√7 - 3√8)
(x√7 - 3√8)(x√7 - 3√8) = (x√7 - 3√8)²
(x√7 - 3√8)² = (x√7)² - 2*x√7*3√8 +(3√8)²
= 7x² - 6x√56 + 72
= 7x² - 6x*2√14 + 72
= 7x² - 12x√14 + 72
Therefore the correct answer is option B). 7x² - 12x√14 + 72
