Rewirte 11/21 and 5/9 so that they have a common denominator

Firdavs [7]

cheap answer is, you <u>multiply one fraction by the other's denominator</u>, so let's do that with both of these fellows.

$\bf \qquad \cfrac{11}{\boxed{21}}~\hspace{21em}\cfrac{5}{\boxed{9}}\\\\[-0.35em] ~\dotfill\\\\ \cfrac{11\cdot 9}{21\cdot 9}\implies \cfrac{99}{189}~\hspace{15em}\cfrac{5\cdot 21}{9\cdot 21}\implies \cfrac{105}{189}$

(5h-4)-(h-5) combining like terms

murzikaleks [220]

Distribute the negative throughout the set of parenthesis

5h-4-h+5

Ok, so your like terms are...

5h and -h

-4 and +5

If you rearrange the terms so that the like terms are next to each other, it is easier to combine them:

5h-h-4+5

5h-h=4h

-4+5=1

So, the problem is:

4h+1

Hope that helps :)

Answer:

Step-by-step explanation:

To find the solutions (or, in other words, zeroes) of a quadratic function/equation we use the discriminant (the part that's inside the square root of the quadratic formula, $b^2-4ac$ .)

If the discriminant is smaller than 0, there are no zeroes

If the discriminant is equal to 0, there is one zero

If the discriminant is larger than 0, it has two zeroes

The discriminant is commonly denoted as $\Delta$ .
