Q. Solve by completing the square.t2−26t+45=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.t=_____ or t=_____
Write Equation Form: Write the equation in the form of t2+bt=c. The given equation is already in this form: t2−26t+45=0.
Move Constant Term: Move the constant term to the right side of the equation.Subtract 45 from both sides to isolate the t2 and t terms.t2−26t=−45
Find Completing Square Number: Find the number to add to both sides to complete the square.Take half of the coefficient of t, square it, and add it to both sides.(−26/2)2=(−13)2=169t2−26t+169=−45+169
Write Perfect Square Trinomial: Write the left side as a perfect square trinomial and simplify the right side.t2−26t+169=124(t−13)2=124
Take Square Root: Take the square root of both sides of the equation.(t−13)2=±124t−13=±124
Solve for t: Solve for t by adding 13 to both sides of the equation.t=13±124Since 124 is approximately 11.14, we can write:t≈13+11.14 or t≈13−11.14t≈24.14 or t≈1.86
