Given is (2x+1)(x−5)

We need to multiply the binomials and write the expression in standard form.

We know about distributive property that is given as "a(b+c) = ab + ac".

We have (2x+1)(x−5).

<u>Step 1: Using Distributive property on first binomial expression (2x+1). </u>

2x(x-5) + 1(x-5)

<u>Step 2: Using Distributive property on second binomial expression (x-5). </u>

2x(x) + 2x(-5) + 1(x) + 1(-5)

2x² - 10x + 1x - 5

<u>Step 3: Combining like terms. </u>

2x² - 9x - 5

Hence, final answer is (2x² - 9x - 5).

How do i solve 2x(n 3) ??
forsale [732]
<span>Simplifying 2x + n = 3
 
Reorder the terms: n + 2x = 3
 Solving n + 2x = 3
 
Solving for variable 'n'.
 
Move all terms containing n to the left, all other terms to the right.
 
Add '-2x' to each side of the equation. n + 2x + -2x = 3 + -2x
 
Combine like terms: 2x + -2x = 0 n + 0 = 3 + -2x n = 3 + -2x
 
Simplifying n = 3 + -2x</span>
