Question

factorise the following:
f) 8a³+4x³
g) 5p²q²-4x³
h) -20x+5x³
I) 15x²y²-30x²y
j) 36abx-45aby​

Answer 1

Answer:

f) 8a³+4x³

= (8a×8a×8a) + (4x×4x×4x)

ans. = 512a+64

g) 5p²-q²-4x³

= (5p×5p) - (q×q) - (4x×4x×4x)

ans.= 10p - 1q - 64x

h). -20x+5x³

= -20x+ (5x×5x×5x)

= -20x + 125x

ans. = 105x

I). 15x²y²-30x²y

= (15x×15x) (y×y) - (30x×30x) y

= 225x 1y - 900x y

= 900x-225x 1y-y

ans. = 675x 0y

j) 36abx - 45 aby

not a equation because variable is different.
