Perform the indicated operation to write given polynomial in standard form: (x+ 2)(2x^2 − 5x+7)

Elan Coil [88]

Answer:

So the expression in standard form will be $2x^3-x^2-3x-14$

Step-by-step explanation:

We have given expression $(x+2)(2x^-5x+7)$

We have to write this expression in standard form

For writing in standard form first we have to multiply the expression

So after multiplication number $(x+2)(2x^2-5x+7)=2x^3-5x^2+7x+4x^2-10x-14=2x^3-x^2-3x-14$

So the expression in standard form will be $2x^3-x^2-3x-14$

Please help! Will award brainliest. Simplify the expression -5+i/2i. Please show your work.

lorasvet [3.4K]

(-5+i)/2i

multiply by i/i

(-5+i) *i = -5i +i^2 = -5i -1

2i*i = 2i^2 = 2(-1) = -2

(-1-5i)/-2

1/2 +5/2 *i

The sum of 3 consecutive even numbers is 132<br><br>pleaase help!!!

agasfer [191]

Answer:

42,44,46

Step-by-step explanation:

we first divide the 132 by the 3 which gives 44

since the numbers involved are even numbers and we know even numbers are numbers divisible by 2 we subtract 2 from the 44 and also add 2 to the 44 the get the rest of the two numbers which is from the above explanation

(44-2),44,(44+2)

42,44,46

we can check whether the above numbers are correct by adding to see whether we get 132

42+44+46=132 which are consecutive even numbers

Multiply all common factors of 9x^6, 15x^4,and 12x^2 to find the GCF.

lesantik [10]

First find common factor for parameters. I mean to find common factor number 9,15,12
first, write the divisors:
Divisors of 9: 1,3,9
divisors of 12: 1,2,3,4,6,12
divisors of 15: 1,2,3,5,15
so see, that GCF of 9,12,15 is 3.

Now, count GCF of x^2, x^4, x^6
GCF 2,4,6 is 2, so the result is x^2
and know finally GCF these terms is $3x^{2}$
