8x²-8x+2-5+x = 8x² - 7x - 3 
Thus, g = 7 and h = 3

Keywords:

<em>polynomial, coefficients, simplify, similar terms </em>

For this case we have to simplify a polynomial, we must find the incognito coefficients of the variable "x" and the independent term. By definition, a polynomial is of the form:

P (x) = ax ^ n + bx ^ {n-1} + ... + cx ^ 3 + dx ^ 2 + ex + f. Where:

a, b, c, d, e, f: They are the coefficients of the polynomial

n, n-1, 3,2,1,0: They are the exponents. And "n" represents the degree of the polynomial, because it is the largest exponent.

x: It is the variable.

So, if we have:

Q (x) = 8x ^ 2 - 8x + 2 - 5 + x

To simplify, we must add similar terms, taking into account that different signs are subtracted and the sign of the major is placed.

Q (x) = 8x ^ 2-8x + x + 2-5\\Q (x) = 8x ^ 2-7x-3

If we compare with the given simplified polynomial, we have:

8x ^ 2 - gx - h

So we have g = 7\ and\ h = 3.

8x ^ 2- (7) x - (3) = Q (x) = 8x ^ 2-7x-3

Answer:

g = 7\ and\ h = 3

A pack of red pens can be divided into equal shares among 3, 5, 6 and 9 teachers with no pen left over?
Ugo [173]

Answer:

90 red pens

Step-by-step explanation:

we need to find the least common multiple of the numbers 3 , 5 , 6 , 9

6 = 2 × 3

9 = 3²

then

LCM(3,5,6,9) = 2×5×3² = 2×5×9 = 90

The number 90 can be divided into 3 ,5 ,6 ,9 with no remainder

Therefore the pack must have 90 pens or a multiple of 90

For example 180 , 270 ...
