Question

Expand the following: a) x(x - 6) b) x(4x + 1) c) 2x(5x + 4) d) 3x(5x - y)

Answer 1

Answer:

Step-by-step explanation:

a. x(x - 6)

x X x - x X 6

x^2 - 6x

b. x(4x + 1)

x X 4x + x X 1

4x^2 + x

c. 2x(5x + 4)

2x X 5x + 2x X 4

10x^2 + 8x

d. 3x(5x - y)

3x X 5x - 3x X y

15x^2 - 3xy

Answer 2

Answer:

[a]=x²_6x

[b]=4x²+x

[c]=10x²+8x

[d]15x²_3xy
