What are the solutions of the equation (2x + 3)2 + 8(2x + 3) + 11 = 0? use u substitution and the quadratic formula to solve

The given expression in single variable is:

⇒Used Distributive property of Multiplication with respect to Addition:

a × (b+c)=a ×b+a × c

⇒For, a Quadratic expression of the form

Ax² +Bx +C=0

Discriminant=D=B²-4 AC

There are two zeroes which are

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
