A- (x+2)(x+3)

B- (a-2)(a-7)

C- (y+6)(y-6)

D- ( 2x-5)(3x-2)

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

F- (-x+4)(x+5)

G- (xy-7)(xy+6)
​

Answer 1

Explicação passo-a-passo:

a) (x+2).(x+3)= x² +3x +2x+6= x²+5x+6

b) (a-2).(a-7)= a² -7a -2a +14=a²-9a+14

c)(y+6).(y-6)= y² -6y +6y - 36= y² - 36

d)(2x-5).(3x-2)= 6x² -4x -15x +10=

6x² -19x +10

e)(1-2x).(4+3x)= 4 +3x -8x - 6x²=

4 - 5x -6x²

f)(-x+4).(x+5)= - x² -5x +4x +20= -x²-x+20

g)(xy-7).(xy+6)= x²y² +6xy -7xy - 42=

x²y²-xy -42
