Determine the value of the coefficient in the following equation:
Determine the value of the coefficient in the following equation:
The quadratic equation in the problem is already arranged (meaning all terms are on one side and 0 on the other side), so let's proceed to answer the question asked:
The question asked in the problem - What is the value of the coefficient in the equation?
Let's recall the definitions of coefficients in solving quadratic equations and the roots formula:
The rule states that the roots of an equation of the form:
are:
That is the coefficient is the coefficient of the quadratic term (meaning the term with the second power)- Let's examine the equation in the problem:
Remember that the minus sign before the quadratic term means multiplication by: , therefore- we can write the equation as:
The number that multiplies the , is hence we identify that the coefficient of the quadratic term is the number ,
Therefore the correct answer is A.
