Answer:

2x²-x-5

Step-by-step explanation:

When multiplying 2 brackets, use the FOIL method. That is, multiply the FIRST terms of each bracket, then the OUTER ones (first term of first bracket and last term of second bracket), INNER (last term of first bracket and first term of second bracket) and finally the LAST terms of each bracket. Thereafter, add up the like terms.

2 1/4 x2 1/4 in mixed number

maks197457 [2]

Answer:

$5 \frac{1}{16}$ is the answer.

Step-by-step explanation:

Given:

$2 \frac{1}{4} \times 2 \frac{1}{4}$

<u>Step 1: Converting the mixed fraction into fraction:</u>

Multiply 4 by 2 add 1 to the result.

<u></u> $2\frac{1}{4}$ = $\frac{4 \times 2+1}{4}$

= $\frac{8+1}{4}$

= $\frac{9}{4}$

<u>Step 2: Performing the multiplication using the fraction</u>

= > $\frac{9}{4} \times \frac{9}{4}$

=> $\frac{81}{16}$

<u>Step 3: Converting the product back to mixed fraction </u>

divide 81 by 16 and find the remainder

=> $quotient \frac{remainder}{divisor}$

Dividing 81 by 16 we get 5 as quotient and 1 as remainder

Thus the result in mixed fraction will be

=> $5 \frac{1}{16}$
