Q. Rewrite the function by completing the square.h(x)=4x2+4x+1h(x)=□(x+□)2+□
Identify coefficients: Identify the quadratic coefficient, linear coefficient, and constant term in the given quadratic function.h(x)=4x2+4x+1Quadratic coefficient (a) = 4Linear coefficient (b) = 4Constant term (c) = 1
Factor out quadratic coefficient: Factor out the quadratic coefficient from the x2 and x terms.h(x)=4(x2+x)+1
Find value to complete the square: Divide the linear coefficient (from the factored form) by 2 and square the result to find the value to complete the square.Linear coefficient in factored form = 1 (after factoring out 4)(21)2=41
Complete the square: Add and subtract the value found in the previous step inside the parentheses to complete the square.h(x)=4(x2+x+41−41)+1
Combine completed square terms: Combine the terms inside the parentheses that complete the square and the term that was subtracted.h(x) = 4((x + \frac{1}{2})^2 - \frac{1}{4}) + 1
Distribute quadratic coefficient: Distribute the quadratic coefficient 4 to the terms inside the parentheses.h(x)=4(x+21)2−4(41)+1
Simplify constant terms: Simplify the constant terms.−4(41)+1=−1+1=0h(x)=4(x+21)2+0
Write in completed square form: Since adding 0 does not change the value, we can write the function in its completed square form.h(x)=4(x+21)2
