Multiply the polynomials (x+4)(x^2-5x+3)

Step-by-step explanation:

Write the polynomials one above the other to multiply them:

Multiply each element of by 4:

The result is: [1]

As it can be seen, only the coefficients are multiplied by 4, and when the operation involves multiplication with coefficients with different operators (+ or -), the following rules are crucial:  

That is why 4 times -5 = -20,  4 times 1 = 4, and so 4 times 3 = 12.

Multiply each element of by x:

The same rules apply here, but including the addition of powers or exponents.

The result is: [2].

or

Sum all similar terms of the previous results [1] and [2].

The result is: , because

do i do it on a graph?

step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
