Question

2. Identify the missing factors:

d) 20 = (4) (?)


e) -14x = (7) (?)


f) x3 =x2 (?)

Answer 1

d) 20 = (4) (5)

e)-14x = (7) (0) = undefined

f) Every Real numbers are solutions, here.

Explanation:

2) Identify the missing factors:-

d) 20 = 4(?)

Solved:

Let us assume that *?* = x here.

• 20 = 4x
• 20/4 = x
• 5 = x
• x =5

e)-14x = (7) (?)

Assume *?* as x

• -14x = 7x
• −14x−7x=7x−7x
• −21x=0
• x = 0/-21 = undefined

f) x^3=x^2(?)

Assume ? as x

• x³=x²(x)
• x³−x³=x^3−x^3
• 0=0
• Real numbers are solutions.
