Multiply the polynomials: (2x + 3)(x - 4)

• 2x^2 - 5x - 12

• 2x^2 + 11x - 12

• 2x^2 - 7x - 12

• 4x^2 - 5x - 12

Factor the polynomial: x^2 - 4

• (x+4)(x-4)

• (x-2)(x-2)

• (x+1)(x-1)

• (x+2)(x-2)

Solve the equation: 2x^2 + 5x - 3 = 0

• x = (-5 + √(5^2 - 4*2*(-3))) / (2*2)

• x = (-5 + √(5^2 + 4*2*(-3))) / (2*2)

• x = (-5 - √(5^2 - 4*2*(-3))) / (2*2)

• x = (-5 ± √(5^2 - 4*2*(-3))) / (2*2)

Identify the polynomial function from the following: f(x) = 2x^3 - 5x^2 + 3x + 1

• f(x) = 2x^2 - 5x^3 + 3x + 1

• f(x) = 2x^4 - 5x^2 + 3x + 1

• f(x) = 2x^3 - 5x^2 - 3x + 1

• f(x) = 2x^3 - 5x^2 + 3x + 1

Simplify the expression: (5x^2 - 3x + 2) - (2x^2 + 4x - 1)

• 7x^2 - 4x + 3

• 4x^2 - 2x + 5

• 2x^2 - 3x + 1

• 3x^2 - 7x + 3

Multiply the polynomials: (3x - 2)(4x + 1)

• 10x^2 + 3x - 2

• 12x^2 - 5x - 2

• 12x^2 + 5x - 2

• 7x^2 + 3x - 2

Factor the polynomial: x^2 + 6x + 9

• (x - 3)^2

• (x + 2)(x + 7)

• (x + 3)^2

• (x + 4)(x + 5)

Solve the equation: x^2 - 9 = 0

• x = ±6

• x = ±4

• x = ±3

• x = ±2

Identify the polynomial function from the following: g(x) = 4x^4 - 2x^2 + 7

• g(x) = 2x^2 + 3x - 1

• g(x) = 6x^3 + 4x^2 - 9x + 1

• g(x) = 4x^4 - 2x^2 + 7

• g(x) = 3x^3 - 5x + 2
