Simplify brackets

(7w - 2 - w = 2(3w - 1)

simplify 7w - 2 - w to 6w - 2

(6w - 2 = 2(3w - 1)

Expand

(6w - 2 = 6w - 2)

Since both sides are equal, there are infinitely many solutions

Answer: C) INFINITELY MANY

Please help me and include step by step!!!<br> (x+9)(x-9) Polynomial identities
WITCHER [35]

Answer:

The given expression is simplified as (x + 9)(x -9)  = x^{2}   - 81

Step-by-step explanation:

Here,the given expression is (x+9)(x -9)

Using the ALGEBRAIC IDENTITY:

(a +b)(a -b)  = a^2  - b^2

Now, here in the given expression (x + 9)(x -9)

Comparing it the left side of the identity,

we get  a  =  x

    and  b = 9

The right side of the equation is a^{2}   - b^{2}

Substituting the value of a and b, we get

⇒ (x + 9)(x -9)  =   (x)^{2}   - (9)^{2}

= x^{2}   - 81

Hence, the given expression is simplified as (x + 9)(x -9)  = x^{2}   - 81
