Q. Solve by completing the square.p2+28p=39Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.p= _____ or p= _____
Rewrite Equation: Rewrite the equation in the form of p2+bp=c. We have the equation p2+28p=39.
Move Constant Term: Move the constant term to the right side of the equation.Subtract 39 from both sides to isolate the p2 and 28p terms.p2+28p−39=0p2+28p=39
Complete the Square:Complete the square by adding the square of half the coefficient of p to both sides.The coefficient of p is 28, so half of it is 14, and the square of 14 is 196.p2+28p+196=39+196
Factor and Simplify: Factor the left side of the equation and simplify the right side.(p+14)2=235
Take Square Root: Take the square root of both sides of the equation.(p+14)2=±235p+14=±235
Solve for p: Solve for p by subtracting 14 from both sides.p=−14±235
Calculate Approximate Values: Calculate the approximate decimal values of p, rounded to the nearest hundredth.235≈15.33p≈−14+15.33 or p≈−14−15.33p≈1.33 or p≈−29.33
