Q. (t+1)2+c=0In the given equation, c is a constant. The equation has solutions at t=23 and t=−27. What is the value of c?
Substitute t=23: Since the solutions to the equation (t+1)2+c=0 are t=23 and t=−27, we can substitute each solution into the equation to find the value of c. First, let's substitute t=23 into the equation. (t+1)2+c=0((23)+1)2+c=0
Calculate value inside parentheses: Now, calculate the value inside the parentheses.(23)+1=23+22=25Now, substitute this value back into the equation.((25)2)+c=0
Isolate c for t=23: Next, calculate the square of 25. (25)2=2252=425 Now, substitute this value back into the equation. 425+c=0
Check t=−27: To find the value of c, we need to isolate c on one side of the equation.c=−(425)This gives us one possible value for c.
Calculate value inside parentheses: Now, let's check the other solution, t=−27, to ensure that it gives us the same value for c.(t+1)2+c=0(−27+1)2+c=0
Isolate c for t=−27: Calculate the value inside the parentheses.(−27)+1=−27+22=−25Now, substitute this value back into the equation.((−25)2)+c=0
Isolate c for t=−27: Calculate the value inside the parentheses.(−27)+1=−27+22=−25Now, substitute this value back into the equation.((−25)2)+c=0Next, calculate the square of −25.(−25)2=(−52)/(22)=425Now, substitute this value back into the equation.(425)+c=0
Isolate c for t=−27: Calculate the value inside the parentheses.(−27)+1=−27+22=−25Now, substitute this value back into the equation.((−25)2)+c=0Next, calculate the square of −25.(−25)2=(−52)/(22)=425Now, substitute this value back into the equation.(425)+c=0Again, to find the value of c, we need to isolate c on one side of the equation.c=−(425)This confirms that the value of c is consistent with both solutions.
