- Q1What is the solution to the equation 2x + 5 = 13?x = 7x = 11x = -4x = 430s
- Q2Which of the following is an identity?(x + 1)^2 = x^2 + x + 1(x + 1)^2 = x^2 - 1(x + 1)^2 = x^2 + 2x + 1(x + 1)^2 = x^2 + 130s
- Q3Which of the following equations has no solution?2x - 5 = 2(x - 5)3x + 2 = 3x + 24x + 7 = 7x + 43x + 4 = 3x - 25x = 2x + 330s
- Q4Which of the following is a conditional equation?4x + 7 = 7x + 43x + 4 = 3x - 25x = 2x + 32x + 7 = 15x^2 + 2x + 1 = (x + 1)^230s
- Q5What is the solution to the equation 5(x - 2) = 3x + 7?x = -2x = 1x = -1x = 230s
- Q6Which of the following equations represents an identity?2x + 3 = 5x - 44x + 7 = 5x + 72(x - 3) = 2x - 63(x - 4) = 3x - 12(x + 1)(x - 1) = x^2 - 130s
- Q7What is the solution to the equation 2x - 5 = 3x + 4?x = -1x = 5x = -9x = 230s
- Q8What is the solution to the equation 3(x + 2) = 5x - 4?x = 8x = -2x = 6x = 330s
- Q9Which of the following equations is equivalent to the identity x^2 - 4 = (x + 2)(x - 2)?x^2 - 4 = x^2 - 4x^2 - 4 = x^2 - 2x - 2x^2 - 4 = x^2 - 2x + 2x^2 - 4 = x^2 + 2x - 2x^2 - 4 = x^2 + 430s
