(x+3/4)(x+3/4)
ANSWER:
(x+3/4)(x+3/4)
REMOVE THE BRACKETS BY MULTIPLYING TERMS.
==> X * X + X * 3/4 + 3/4 * X + 3/4 * 3/4
==> X^2 + (3/4) * X + (3/4) * X + 9/16
==> X^2 + (3/4 +3/4) * X + 9/16
==> X ^2 + (6/4)* X + 9/16
MULTIPLY THE WHOLE EXPRESSION BY 16.
==> 16 X^2 + 16 * 6/4 * X + 16 * 9/16
==> 16X^2 + 24X + 9
THAT IS,
(x+3/4)(x+3/4) = 16X^2 + 24X + 9
