x^2 - 6x + __ = -13 + __
take half of the coefficient in ur x term, square it, and add it to both sides
so take half of -6 which is -3 and square it -3^2 = 9. Now add 9 to both sides.
x^2 - 6x + 9 = -13 + 9
(x - 3)^2 = - 4
What is an example of a coefficient?
For example, within the expression 3x, three is the coefficient of x but within the expression x2 + 3, 1 is the coefficient of x2. In other words, a coefficient is a multiplicative issue inside the terms of a polynomial, a sequence, or any expression.
Conclusion: A coefficient is quite a number this is being extended by way of the variable. 2x+6x+14. The 2x, 6x, and 14 are phrases because they're being introduced collectively. 2 and x; 6 and x are factors due to the fact they're being accelerated collectively. 2 from 2x and 6 from 6x are the coefficients due to the fact they are being elevated with the aid of the variable.
