## How do you factor 4x 2 1?

Rewrite 4×2 4 x 2 as (2x)2 ( 2 x ) 2 . Rewrite 1 as 12 . Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 – b 2 = ( a + b ) ( a – b ) where a=2x a = 2 x and b=1 .

## What is the coefficient in 3x 15?

3x = 15 can be solved with the Multiplication Property of Equality. In order to solve this equation, x must be isolated. So, if we multiply both sides by 1/3, then x’s coefficient will become 1. 15 times 1/3 (15 * 1/3 = 15/3) equals 5.2019-10-09

## What makes an equation false?

A false equation is an incorrect equation; it says something erroneous or untrue. For example, 2 = 3 is a false equation, because 2 and 3 are different numerical values. To make a true equation, check your math to make sure that the values on each side of the equals sign are the same.2017-04-24

3 x 15 =
45

## How do you factor x4 25?

Rewrite x4 as (x2)2 ( x 2 ) 2 . Rewrite 25 as 52 . Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 – b 2 = ( a + b ) ( a – b ) where a=x2 a = x 2 and b=5 .
