Q. Which equation has the same solution as x2+4x−16=−4 ?(x−2)2=16(x+2)2=16(x−2)2=8(x+2)2=8
Simplify Equation: First, we need to simplify the given equation x2+4x−16=−4 by moving all terms to one side to set the equation to zero.x2+4x−16+4=0x2+4x−12=0
Factor Quadratic: Now, we need to factor the quadratic equationx2+4x−12. We look for two numbers that multiply to −12 and add up to 4. These numbers are 6 and −2. (x+6)(x−2)=0
Find Solutions: Next, we set each factor equal to zero to find the solutions for x.x+6=0 or x−2=0So, x=−6 or x=2
Compare with Choices: Now, we need to compare the solutions x=−6 and x=2 with the choices given to see which equation has the same solutions.The choices are:1. (x−2)2=162. (x+2)2=163. (x−2)2=84. (x+2)2=8
Analyzing Choice 1: Let's analyze the first choice: x - 2)^2 = 16\. Taking the square root of both sides, we get \$x - 2 = \pm4. So, x=2+4 or x=2−4, which gives us x=6 or x=−2. This does not match our solutions of x=−6 or x=2.
Analyzing Choice 2: Next, let's analyze the second choice: (x+2)2=16. Taking the square root of both sides, we get x+2=±4. So, x=−2+4 or x=−2−4, which gives us x=2 or x=−6. This matches our solutions of x=−6 or x=2.
No Need to Analyze: We do not need to analyze the 3rd and 4th choices because we have already found a match with the 2nd choice.
