Patel is solving 8x2 + 16x + 3 = 0. Which steps could he use to solve the quadratic equation? Select three options.

MakcuM [25]

Answer:

<em>8(x2 + 2x) = –3 </em>

<em>8(x2 + 2x + 1) = –3 + 8 </em>

<em>x = –1 Plus or minus StartRoot StartFraction 5 Over 8 EndFraction EndRoot</em>

Step-by-step explanation:

<u>Solving Quadratic Equations </u>

Sometimes it's preferred to solve quadratic equations without the use of the known quadratic formula solver. One of the most-used methods consists of completing squares and solving for x.

We have the equation

$\displaystyle 8x^2+16x+3=0$

We separate variables from constants

$\displaystyle 8x^2+16x=-3$

Taking the common factor 8

$\displaystyle 8(x^2+2x)=-3$

Completing squares in the brackets and balancing the equation in the right side

$\displaystyle 8(x^2+2x+1)=-3+8$

Factoring the perfect square

$\displaystyle 8(x+1)^2=5$

Isolating x

$\displaystyle (x+1)^2=\frac{5}{8}$

$\displaystyle (x+1)=\pm \sqrt{\frac{5}{8}}$

$\displaystyle x=-1\pm \sqrt{\frac{5}{8}}$

We can clearly see the steps used to solve the quadratic equation are (in order and written like in the question)

8(x2 + 2x) = –3

8(x2 + 2x + 1) = –3 + 8

x = –1 Plus or minus StartRoot StartFraction 5 Over 8 EndFraction EndRoot

I'm struggling with this question i need help. please and thank you

soldi70 [24.7K]

The answer is 100X because if you do 5x-4x first it will be 1x. Later on, if you do the exponent you have 1x times 1x. Then you do 1x+9x = 10x

Then you do 10x times 10x because of the exponent is telling you how times you do it and it equals to 100x.

Answer= 100x

I hope this helps YOU!

Answer:

x≤ -7 or x≥ -4

Step-by-step explanation:

There is a closed circle at -7 and the line goes to the left

x≤ -7

There is a closed circle at -4 and the line goes to the right

x≥ -4

Since they both can't be true at the same time it is an or

x≤ -7 or x≥ -4
