Question

(3a-4b+2c)-(4a-5c+2b) please simplify this polynomial @midhun.madhu1987 can u help w/ this?

Answer 1

or anyone..

Answer 2

Simplify the following:
\[3 a-4 b+2 c-(4 a-5 c+2 b) \]Distribute -1 over \( 4 a+2 b-5 c\).
\[-(4 a+2 b-5 c) = -4 a-2 b+5 c: \]\[3 a-4 b+2 c+-4 a-2 b+5 c \]Group like terms in \(3 a-4 b+2 c-4 a-2 b+5 c.\)
Grouping like terms, \(3 a-4 b+2 c-4 a-2 b+5 c = (2 c+5 c)+(-4 b-2 b)+(3 a-4 a):\)
\[(2 c+5 c)+(-4 b-2 b)+(3 a-4 a) \]Add like terms in \(2 c+5 c.\)
\[2 c+5 c = 7 c: \]\[7 c+(-4 b-2 b)+(3 a-4 a) \]Combine like terms in \(-4 b-2 b.\)
\[-4 b-2 b = -6 b: \]\[7 c+-6 b+(3 a-4 a) \]Combine like terms in \(3 a-4 a.\)
\[3 a-4 a = -a: \]

Which leaves you with...?

Answer 4

thank you, i get it now, can you help me with another? @DangerousJesse

Answer 5

Sure

Answer 6

1)Factor each expression completely. x^2-5x-14

Answer 7

2)Factor each expression completely.
m^2-100

Answer 8

@DangerousJesse

Answer 9

Factor the following:
\[x^2-5 x-14 \]Factor \(x^2-5 x-14\) by finding two numbers whose product is \(-14\) and whose sum is \(-5\).
The factors of \(-14\) that sum to \(-5\) are \(2\) and \(-7\). So, \(x^2-5 x-14 = (x+2) (x-7):\)

Answer 10

So, your answer is?

Answer 11

(-2 + -1x)(7 + -1x)

Answer 12

\[(x+2)(x-7)\]
