Select the correct answer. Which expression is equivalent to the given polynomial expression? (-4a2 â€"" 3b) + (-2ab -a2 +b2) + (-b2+ 6ab)

OA.-3a2 +2b2 + 8ab + 3b
OB.-3a2 + 4ab + 3b
O c. -5a2 + 4ab - 3b
D.-5a2 + 2b2 + 8ab + 3b​

answer: it is 8

step-by-step explanation:

you know why its 8

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
