Question

.
Simplify: a (a'+a+1)+5 and find its value for (i) a=0 (11) a= -1
OR
Subtract: 3a (a + b + c)-2 b (a - b + c) from 4c (- a+b+c)
Identify the top view, front view and side view​

Answer 1

Answer:

(i) 6 (11) -1

Step-by-step explanation:

0(0+0+1)+5=6

-1(-1-1+1)+5=1(5)=5

Answer 2

Step-by-step explanation:

(i) a(a+a+1)+5 a=0

0(0+0+1)+5

open the brackets

(0x0)+(0x0)+(0x1)+5

0+0+0+5

=5

(ii) a(a+a+l)+5 a= -1

-1(-1+-1+1)+5

open the brackets

(-1x-1)+(-1x-1)+(-1x1)+5

1+1+-1+5

2+-1+5

=6

OR

4c(-a+b+c) - 3a(a+b+c)-2b(a-b+c)

-4ca+4cb+4c² - 3a²+3ab+3ac-2ba+2b²-2b

first solve the right side

-4ca+4cb+4c² - 3a²+2b²+3ab-2ba+3ac-2bc

-4ca+4cb+4c² - 3a²+2b²+ab+3ac-2bc

now solve both the sides

-4ca+3ac+4cb-2bc+4c²-3a²+2b²+ab

-ac+2bc+4c²-3a²+2b+ab
