MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Solve the quadratic equation by factoring: x2−5x+6=0x^2 - 5x + 6 = 0 .

x=2,3x = 2, 3

x=1,6x = 1, 6

x=−2,−3x = -2, -3

x=3,2x = 3, 2

Answer explanation

To solve the quadratic equation by factoring x^2 - 5x + 6 = 0, we need to find two numbers that multiply to 6 and add up to -5. These numbers are -2 and -3, so the solutions are x = 2, 3.

Factor the quadratic expression 4x2−4x−84x^2 - 4x - 8 .

4(x2−x−2)4(x^2 - x - 2)

2(x−2)(x+2)2(x - 2)(x + 2)

4(x−2)(x+1)4(x - 2)(x + 1)

4(x+2)(x−1)4(x + 2)(x - 1)

Answer explanation

Choose 4 as the common factor and factor the quadratic expression to get 4(x - 2)(x + 1).

Factor the quadratic expression x2+6x+9x^2 + 6x + 9 .

(x+3)2(x + 3)^2

(x−3)2(x - 3)^2

(x+3)(x−3)(x + 3)(x - 3)

(x+4.5)2(x + 4.5)^2

Answer explanation

To factor the quadratic expression x^2 + 6x + 9, we recognize that it is a perfect square trinomial, which factors to (x + 3)^2.

Solve the quadratic equation by factoring: 3x2+18x+27=03x^2 + 18x + 27 = 0 .

x=−3x = -3

x=3x = 3

x=−6,−3x = -6, -3

x=−3,3x = -3, 3

Answer explanation

To solve the quadratic equation by factoring, we can factor out a common factor of 3 from all terms to get (x + 3)^2 = 0. Solving for x gives x = -3.
