bantu ya, sebisanya;;) makasiih

Answer 1

A) (2x + 5) (x + 3) b) (2x + 3) (x - 4) c). (3x + 1) (x + 3) d). ( 2x - 1) (2x - 16) e). f). (2x + 4) (x - 5) G). (4x - 1) (x + 3) H). (6x + 16) ( x - 1)

Answer 2

B. 2x2 - 5x - 12
= 2x2 - 8x + 3x - 12
= 2x (x - 4) + 3 (x - 4)
= (2x + 3)(x - 4)
c. 3x2 + 10x + 3
= 3x2 + 9x + 1x + 3
= 3x (x + 3) + 1 (x + 3)
= (3x + 1)(x + 3)
d. 4x2 - 34x + 16
= 4x2 - 32x - 2x + 16
= 4x (x - 8) - 2 (x - 8)
= (4x - 2)(x - 8)
f. 2x2 - 6x - 20
= 2x2 + 4x - 10x - 20
= 2x (x + 2) - 10 (x + 2)
= (2x - 10)(x + 2)
g. 4x2 + 11x - 3
= 4x2 + 12x - 1x - 3
= 4x (x + 3) - 1 (x + 3)
= (4x - 1)(x + 3)
itu aja yg aq bisa tpi maaf ya klo ada yg salah
