Q. Solve by completing the square.k2+2k−35=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.k= _____ or k= _____
Rewrite and Add Constant:k2+2k−35=0Rewrite the equation in the form of x2+bx=c.Add 35 to both sides to move the constant term to the right side of the equation.k2+2k−35+35=0+35k2+2k=35
Complete the Square:k2+2k=35Choose the number to add to both sides to complete the square.Since (2/2)2=1, add 1 to both sides.k2+2k+1=35+1k2+2k+1=36
Identify Factored Form:k2+2k+1=36Identify the equation after factoring the left side.k2+2k+1=36(k+1)2=36
Take Square Root:(k+1)2=36Identify the equation after taking the square root on both sides.Take the square root of both sides of the equation.(k+1)2=36k+1=±36k+1=±6
Isolate Variable: We found:k+1=±6Choose the equation after isolating the variable k.To isolate k, subtract 1 from both sides of the equation.k+1−1=±6−1k=−1±6
Find Values of k: We have:k=−1±6What are the two values of k?k=−1+6 implies k=5.k=−1−6 implies k=−7.Values of k: 5, −7
