Working together in pairs

−4(x−7)=

1. 4x+24
2. −4x−28
3. −4x+28
4. −4x−24

Note: how to write down the order

10−2(x−7)=

(only type in the answer, without spaces)

8−3(x+7)=

(only type in the answer, without spaces)

−3(x−3)−5(x+6)=

Note: Working away double brackets

(a+5)(a−7)=

(x−6)​2​​=

(a+6)(a−7)=

1. a​2​​−a+48
2. a​2​​−a−42
3. a​2​​−a−1
4. a​2​​−1a+42

(only type in the answer, without spaces)
(x squared = x^2)

(x−3)(x+5)=

(c−6)(−3+c)=

1. c​2​​−9c+18
2. −c​2​​−9c+2
3. c​2​​+9c−18
4. −c​2​​−9c−18

(only type in the answer, without spaces)
(x squared = x^2)

(x−3)​2​​=
