The factorization of the given equation 2 x^{2}-6 x+4 \text { is }(2 x-4)(x-1)

<u>Solution:</u>

We have been given an equation as follows:

2 x^{2}-6 x+4

We need to completely factorize it.

According to the definition of factorization we understand, a polynomial can be written as a product of two or more polynomials of degree less than or equal to that of it.

The process involved in breaking a polynomial into the product of its factors is known as the factorization of polynomials.

So, we factorize the equation according to the definition as follows:

\begin{array}{l}{=2 x^{2}-6 x+4} \\\\ {=2 x^{2}-2 x-4 x+4} \\\\ {=2 x(x-1)-4(x-1)} \\\\ {=(2 x-4)(x-1)}\end{array}

We can find the roots of the given equation as follows:

\begin{array}{l}{2 x-4=0} \\\\ {x=\frac{4}{2}=2}\end{array}

x - 1 = 0

x = 1

Therefore, the factorization of the given equation is (2x - 4)(x - 1)

Heidi solved the equation 3(x + 4) + 2 = 2 + 5(x – 4). Her steps are below: 3x + 12 + 2 = 2 + 5x – 20 3x + 14 = 5x – 18 14 = 2x
lyudmila [28]

Answer:

See explanation

Step-by-step explanation:

3(x + 4) + 2 = 2 + 5(x – 4)

Step 1: distributive property

3(x + 4) + 2 = 2 + 5(x – 4)

3x + 12 + 2 = 2 + 5x - 20

Step 2: collect like terms

3x + 12 + 2 = 2 + 5x - 20

3x + 14 = 5x - 18

Step 3: Addition property of equality

3x + 14 = 5x - 18

3x + 14 + 18 = 5x - 18 + 18

3x + 32 = 5x

Step 4: subtraction property of equality

3x + 32 - 3x = 5x - 3x

32 = 2x

Step 5: division property of equality

32 = 2x

32/2 = 2x/2

16 = x

x = 16
