Q. Find one value of x that is a solution to the equation:(x2+3)2=4x2+12x=□
Expand left side of equation: We are given the equation (x2+3)2=4x2+12. To find the value of x, we need to simplify and solve the equation.First, let's expand the left side of the equation using the formula (a+b)2=a2+2ab+b2.(x2+3)2=(x2)2+2(x2)(3)+(3)2
Perform calculations: Now, let's perform the actual calculations:(x2+3)2=x4+2(3x2)+9This simplifies to:x4+6x2+9
Equate to right side of equation: Next, we equate the expanded form to the right side of the original equation: x4+6x2+9=4x2+12
Move terms to one side: Now, we need to move all terms to one side to set the equation to zero and solve for x:x4+6x2+9−4x2−12=0
Combine like terms: Simplify the equation by combining like terms: x4+2x2−3=0
Substitute y=x2: This is a quadratic equation in terms of x2. Let's substitute y=x2 to make it easier to solve:y2+2y−3=0
Factor the quadratic equation: Now, we factor the quadratic equation:(y+3)(y−1)=0
Solve for y: Set each factor equal to zero and solve for y:y+3=0 or y−1=0
Substitute back to find x: Solving for y gives us two solutions: y=−3 or y=1
Solve for x: Since y=x2, we substitute back to find the values of x:x2=−3 (This is not possible since x2 cannot be negative for real numbers.)x2=1
Solve for x: Since y=x2, we substitute back to find the values of x:x2=−3 (This is not possible since x2 cannot be negative for real numbers.)x2=1 Solve for x when x2=1:x=1 or x=−1x=1 or x0
