Question

29. 4x4 – x2 - 12x - 36
30. a2 (b + c) - (b + c)3
factorize with using identity...with proper steps ...plzz anyone help me ​

Answer 1

Answer:

I think your question no. 19 is wrong.

Step-by-step explanation:

30.

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

Answer 2

29.

4x4 - x2 - 12x -36

(2x2)^2 -(x2+12x+36)

from identity x2+y2+2xy = (x+y)2

(2x2)^2 - (x+6)^2

from identity x2-y2 = (x+y)(x-y)

(2x2+x+6)(2x2-x-6)

this answer will be correct but it can be further factorized as well

(2x2+x+6)(2x2-x-6)

(2x2 +x+6)(2x2-4x+3x-6)

(2x2+x+6)( 2x(x-2)+3(x-2))

(2x2+x+6)(2x+3)(x-2)---------ANS

30.

a2(b+c) - (b+c)3

(b+c)(a2-(b+c)2) by identity a2-b2= (a+b)(a-b)

(b+c)(a+b+c)(a-b-c)---------ANS

mark me the brainiest ...because why not?
