2x^2+ 9x +4=
factor the expression

(x+4)(2x+1)

Step-by-step explanation:

1. 2x^2+8x+x+4 split the second term in 2x^2 + 9x+4 into two terms.

2. 2x(x+4)+(x+4) Factor out common terms in the first two terms, then in the last two terms.

3.(x+4)(2x+1) factor out the common term x+4

Step-by-step explanation:

Here's some steps.

A straight line segment can be drawn joining any two points. Any straight line segment can be extended indefinitely in a straight line. The whole is equal to the sum of its parts. All right angles are congruent (equal in measure).

In two dimensions there are 3 geometries: Euclidean, spherical, and hyperbolic. These are the only geometries possible for 2-dimensional objects, although a proof of this is beyond the scope of this book.

Hope this helps!
