The model represents the factorization of 2x2 + 5x + 3. What is the missing term in the factorization of 2x2 + 5x + 3? (2x + 3)(x + )

Respuesta :

we have

[tex] 2x^{2} + 5x + 3 [/tex]

equate the expression to zero

[tex] 2x^{2} + 5x + 3 =0 [/tex]

Group terms that contain the same variable, and move the constant to the opposite side of the equation

[tex] 2x^{2} + 5x =-3 [/tex]

Factor the leading coefficient

[tex] 2(x^{2} + 2.5x) =-3 [/tex]

Complete the square. Remember to balance the equation by adding the same constants to each side

[tex] 2(x^{2} + 2.5x+1.5625) =-3+3.125 [/tex]

[tex] 2(x^{2} + 2.5x+1.5625) =0.125 [/tex]

Rewrite as perfect squares

[tex] 2(x+1.25)^{2} =0.125 [/tex]

[tex] (x+1.25)^{2} =0.0625 [/tex]

[tex] (x+1.25) =(+/-)\sqrt{0.0625} \\ x1=-1.25+\sqrt{0.0625}\\ x2=-1.25-\sqrt{0.0625} [/tex]

Simplify

[tex] x1=-1.25+\sqrt{0.0625}\\ x1=-1.25+0.25\\ x1=-1 [/tex]

[tex] x2=-1.25-\sqrt{0.0625}\\ x2=-1.25-0.25\\ x2=-1.50 [/tex]

[tex] 2x^{2} + 5x + 3=2(x+1.5)(x+1)\\ =(2x+3)(x+1) [/tex]

therefore

the answer is

the missing term in the factorization is [tex] 1 [/tex]

The missing term in the factorization of the given quadratic expression (2x² + 5x + 3) is determined as (x + 1).

Factorization of the quadratic equation

The given quadratic equation can be factorized as follows;

2x² + 5x + 3

2x²  + 2x + 3x + 3  (5x = 2x + 3x)

factorize similar terms together

2x(x + 1) + 3(x + 1)

The factorized form = (2x + 3)(x + 1)

Thus, the missing term in the factorization of the given quadratic expression (2x² + 5x + 3) is determined as (x + 1).
