Complete the square for the expression. Also, identify the resulting expression as a binomial squared. x2 + 11x +

When completing the square is carried out on the quadratic we get

when expressed as a binomial squared, we get

To complete the square, we need to add a term to the expression

that would make it a perfect square. Generally, given the quadratic expression

to make it a perfect square, we have to add half the square of the coefficient of . That is, add , or to the quadratic expression to get

which, when factored into a binomial squared becomes

In our case, the quadratic will become

and when expressed as a binomial squared, we get

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
