Write each of the following quadratic expressions as a product of linear factors. verify that the factored form is equivalent. a)x²+12x+27b)x²-16c)x²+16d)x²+4x+5

(a) (x+3) (x+9)

(b) (x+4) (x-4)

(c) (x-4i) (x+4i)

(d) (-2+i) (-2-i)      

Step-by-step explanation:

We have given the quadratic expressions and we have to write these expressions in factor form

(a)

It can be written as

Now taking (x+9) as common

(b)

We know the algebraic equation

(c)

(d)

It can be written as

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
