Question

5. Multiply the following by column method
(i) (5m – 3n) (4m + 6n)
(ii) (5x' + 4y ) (3x - 5y?)
(ii) (4x' +2y- 6xy) x (x – 3y* + 2xy)
(iv) (3a + 4b-6c) (4a -9b+8c)
please solve step by step ​

Answer 1

Answer:

i)9m+3n

ii)8x-1y

iii)5x-1y-4xy

iv)7a+13b+2c

Step-by-step explanation:

i) First open the brackets and then arrange the values and solve the rest

5m-3n+4m+6n

5m+4m-3n+6n

9m+3n

ii)First open the brackets then arrange the values and solve the rest

5x+4y+3x-5y

5x+3x+4y-5y

8x-1y

iii)First open the brackets then arrange the values and solve the rest

4x+2y-6xy×x-3y+2xy

4x+x+2y-3y-6xy+2xy

5x-1y-4xy

iv)3a+4b-6c+4a-9b+8c

3a+4a+4b+9b-6c+8c

7a+13b+2c
