Question 1184587
<br>
IF by standard form you mean<br>
y=ax^2+bx+c<br>
then the question can be answered.<br>
Note, however, that the standard form for a quadratic is not always expressed in that form. So it is technically a defective post if you simply ask for the value of a.<br>
And if you are indeed talking about that standard form, there is no need to expand and/or simplify the entire equation.<br>
a is the coefficient of the x^2 term and is simply the product of the constant coefficient (if any) and the coefficients of the x terms in each binomial factor.<br>
In your example the constant coefficient is 1, and there are two binomial factors, both of which have coefficient 1.  So the value of a is<br>
(1)(1)(1) = 1.<br>
ANSWER: a=1<br>
