Simplify. 98^(2) - 4 = ?

Calculate Right Side: Calculate the right side of the equation, which is 98^2 - 4. First, calculate 98^2, which is 98 multiplied by 98. 98 * 98 = 9604 Then subtract 4 from 9604. 9604 - 4 = 9600Rewrite Equation: Rewrite the equation with the calculated value on the right side. 285x = 9600Solve for x: Solve for x by dividing both sides of the equation by 285. To isolate x, divide 9600 by 285. x = 9600 / 285Perform Division: Perform the division to find the value of x. x = 9600 / 285 x = 33.68421052631579 However, since we are likely looking for a simplified or rounded answer, we can round this to x = 33.68 if we round to two decimal places.
