Question

using suitable identities,determine the product:
$( x + \frac{3}{4} )( x + \frac{3}{4} )$
​

Answer 1

Answer:

IDENTITY TO BE USED:

$({x + y})^{2} = {x}^{2} + {y}^{2} + 2xy$

SOLUTION:

$({x + \frac{3}{4} })^{2} = {x}^{2} + {( \frac{3}{4} })^{2} + 2 \times x \times \frac{3}{4} \\ \\ = {x}^{2} + \frac{9}{16} + \frac{3x}{2}$
