Exercise 11 (E) | Q 25

Subtract the sum of 3a² – 2a + 5 and a² – 5a – 7 from the sum of 5a² -9a + 3 and 2a – a² – 1

If x = 4a² + b² - 6ab; y = 3b² - 2a² + 8ab and z = 6a² + 8b² - 6ab find: x + y + z

If x = 4a² + b² - 6ab; y = 3b² - 2a² + 8ab and z = 6a² + 8b² - 6ab find: x - y - z

If m = 9x² - 4xy + 5y² and n = - 3x² + 2xy - y² find: m - 3n

Simplify: 4x + 7y - (5y - 8) - 2x

Simplify: 4(3x - 8) - 3(5x + 3) - 2(6x - 8)
