Nancy found that x=1 is one solution to the quadratic equation (x 2)2=a. what is the value of a? -9 -3 3 9

AlladinOne [14]

The value of the <em>a, </em>in the provided quadratic equation for which Nancy found one solution as x=1 is 9.

<h3>What is the solution of equation?</h3>

The solution of the quadratic equation is the solution of the variable of the equation, for which the equation satisfies.

Nancy found that x=1 is one solution to the quadratic equation. The quadratic equation is,

$(x +2)^2=a$

For this equation, one solution is <em>x</em>=1. Put this value in the above equation to get the value of <em>a,</em>

$(1 +2)^2=a\\(3)^2=a\\9=a\\a=9$

Thus, the value of the <em>a, </em>in the provided quadratic equation for which Nancy found one solution as x=1 is 9.

What is the difference of the two expressions?

valkas [14]

<em>Answer is x + 12</em>

<em />

<h2>Explanation:</h2>

Hello! Recall that you have to write clear questions in order to get exact answers. So I'll help you assuming that the two expressions are the following:

First expression:

$2x+9$

Second expression:

$x-3$

So the operation we need to perform is:

$2x+9-(x-3)$

Recall some rules:

$(+)\times (+)=+ \\ \\ (-)\times (-)=+ \\ \\ (-)\times (+)=- \\ \\ (+)\times (-)=-$

Hence:

$2x+9-(x-3)=2x+9-x+3 \\ \\ \\ Combine \ like \ terms: \\ \\ (2x-x)+(9+3) \\ \\ \boxed{x+12}$
