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 $(x+2)(x-18)=0$

Find the area of a rectangle with a length of 4 5/8 inches and a width of 1/2 inch? Is it A. 16/37 in2, B. 37/16 in2, C. 37/2 in

dybincka [34]

Area is length times width. Our length and width are 4 5/8 and 1/2 respectively, so the formula for the area is $A=4 \frac{5}{8}* \frac{1}{2}$ . It will be easier to get that mixed fraction into an improper one and then multiply the fractions straight across the top and straight across the bottom. $A= \frac{37}{8}* \frac{1}{2}$ . Doing that multiplication gives us $A= \frac{37}{16}$ , choice B.
