Write the expression 7x^10 + 6x^5 + 5 in quadratic form.a 7x P) + 6x +5
7x10 + 6(x+0 x
6. 7(x)* +6x? +5
7720 + 6(220)2 = 5

Answers

For this case we have the following expression:

$7x^(10) + 6x ^ 5 + 5$

We must rewrite it quadratically:

By definition, a quadratic equation is of the form:

$ax ^ 2 + bx + c = 0$

Now, suppose $u = x ^ 5$

Rewriting the given expression with the change of variable we have:

$7u ^ 2 + 6u + 5$

So, we have a quadratic expression.

Returning the change we have:

$7 (x ^ 5) ^ 2 + 6 (x ^ 5) +5$

ok so what y ou want to do it to max space, lie it diagonally
use pythagoren theorem
first convert the units

4'=4 feet
8''=8 inches
convert to inches
4 feet times 12=48 inches

so
pythagorea theorem is
a^2+b^2=c^2
c=hypotonuse
a and b are legs
in a right triangle

8 and 48 are the legs
fidn hypotonuse

8^2+48^2=c^2
64+2304=c^2
2368=c^2
8√37=c
aprox
48.66=c
