Question

Factorize (i) 16(X+Y)^2

-40(X+Y)(X–Y) +25(X-Y)^2
​

Answer 1

Answer:

(-9x - 11y) • (x + 19y)

Step-by-step explanation:

16 • ((x - y)2)) - 25 • (x + 3y)2

16 • (x - y)2 - 25 • (x + 3y)2

Evaluate : (x-y)2 = x2-2xy+y2

Evaluate : (x+3y)2 = x2+6xy+9y2

-9x2 - 182xy - 209y2 = -1 • (9x2 + 182xy + 209y2)

9x2 + 182xy + 209y2

Try to factor this multi-variable trinomial using trial and error

Found a factorization : (9x + 11y)•(x + 19y)

(-9x - 11y) • (x + 19y)
