Question

A (a-2)(a-7)

B (y+6)(y-6)

C (2x-5)(3x-2)

D (1-2x)(4+3x)

E (-x+4)(x+5)

F (2x+y)(x-y)

G (xy-7)(xy+6)

Answer 1

A (a-2)(a-7)

a² - 7a - 2a + 14

a² - 9a + 14

B (y+6)(y-6)

y² - 6y + 6y - 36

y² - 36

C (2x-5)(3x-2)

6x² - 4x - 15x + 10

6x² - 19x + 10

D (1-2x)(4+3x)

4 + 3x - 8x - 6x²

4 - 5x - 6x²

- 6x² - 5x + 4

E (-x+4)(x+5)

- x² - 5x + 4x + 20

- x² - x + 20

F (2x+y)(x-y)

2x² - 2xy + xy - y²

2x² - xy - y²

G (xy-7)(xy+6)

x²y² + 6xy - 7xy - 42

x²y² - xy - 42
