What is the intermediate step in the form (x+a)^2=b as a result of completing the square for the following equation? Please help

barxatty [35]

Answer:

${( \bold {\purple{ \boxed{ x + 7}}})}^{2} = \: \bold {\purple{ \boxed{ 9}}}$

Step-by-step explanation:

$- 2 {x}^{2} - 28x = 80 \\ \\ - 2( {x}^{2} + 14x) = 80 \\ \\ {x}^{2} + 14x = - 40 \\ \\ {x}^{2} + 2.x. \bold{ \red{7 }}+ 49 = - 40 + 49 \\ (add \: square \: of \: 7 \: both \: sides)\\ \\ {x}^{2} + 14x + {7}^{2} = 9 \\ \\ {( \bold {\purple{ \boxed{ x + 7}}})}^{2} = \: \bold {\purple{ \boxed{ 9}}}$

Well something for example.Would be if you were a contactor,you need to find measurements of lots of things. For example that could be needing to find the sum of 2 sides.And find the sum of the 2 sides of that right trainagle can determine if the biulding has a good foundation . And thats how you can use a Pythagorean Theorem in the real world !

Evaluate the piecewise function below for f(1):

lorasvet [3.4K]

We need to find f(1)

f(1) means x=1

Now we look at the three inequalities and choose the one where x=1 satisfies

x<=-1 , -1<x<1 and x>=1

x=1 satisfies the inequality x>=1

so we use the third function to find f(1)

$f(x) = 2x^2 + 3$

We plug in 1 for x and find f(1)

$f(1) = 2(1)^2 + 3$ = 2 + 3 = 5

f(1) = 5
