What is x2 – 6 = 16x + 30 rewritten in standard form, then factored?
AlexFokin [52]

Answer:

The standard form of quadratic equation is x^2-16x-36=0

The factored form of x^2-16x-36=0 is (x+2)(x-18)=0

Step-by-step explanation:

Given equation x^2-6=16x+30

We have to write  in standard form and then factorize the given equation.

The standard form for a general quadratic equation is given as ax^2+bx+c=0

Consider x^2-6=16x+30

Taking all terms to left side, we have,

x^2-6-16x-30=0

Adding like terms, we have,

x^2-16x-36=0

Now we will factorize it.

We will solve the quadratic equation x^2-16x-36=0 using middle term splitting method,

-16x can be written as -18x+2x

x^2-16x-36=0  becomes

\Rightarrow x^2-18x+2x-36=0

Taking x common from first two terms  and 2 common from last two terms we have,

\Rightarrow x(x-18)+2(x-18)=0

\Rightarrow (x+2)(x-18)=0

Thus, the factored form of x^2-16x-36=0 is (x+2)(x-18)=0

A valet makes $53 each day he works and approximately $7 in tips for each car he parks. if he wants to make at least $186 in one
eimsori [14]

Answer:

19 Cars

Step-by-step explanation:

Write a linear equation:

y=7x+53

Y = Total money

X = cars parked

If we want to earn 186 dollars a day then sub y for 186 and solve x:

186=7x+53

186-53=7x

133=7x

7x=133

x=133/7

x=19

This means that he will need to park 19 cars a day to earn a total of 186 dollars in one day.
