Maths for Class 8th: Algebraic Expressions

Simplify the expression: 3x + 2y - 5x + 4y

• x + 2y

• -2x + 6y

• -5x + 6y

• -2x + 3y

Factorize the expression: 6x^2 - 11x + 4

• (2x - 3)(3x - 1)

• (6x - 11)(x + 4)

• (2x - 4)(3x - 1)

• (3x - 2)(2x - 1)

Expand and simplify the expression: (2x + 3)(x - 4)

• 2x^2 - 8x + 3x + 12

• 2x^2 - 8x + 3x - 4

• 2x^2 - 8x + 3x - 12

• 2x^2 - 8x + 3x - 16

Combine like terms: 5a^2b - 2ab^2 + 3a^2b + ab^2

• 8a^2b - ab^2

• 5a^2b - 2ab^2 + 3a^2b

• 3a^2b - ab^2

• 2a^2b - 3ab^2

Solve for x: 2(x + 4) = 3(x - 1)

• x = 11

Simplify the expression: 4(2x - 3) - 2(3x + 1)

• 2x - 14

• x - 7

• 8x - 12

• 6x - 10

Solve for x: 5(x - 2) = 3(x + 4)

• x = -6
