Question

What is the answer for "1a*a=9a?"..please give me a correct answer.... 1a*a = 9a​

Answer 1

a = 9, a = 0

Explanation:

a1 can be solved without factoring:

• 1a*a = 9a
• a^2 = 9a
• a = 9 (divide both sides by a)

a is also 0 since both sides only contain single terms with the same variable. This can too be found by subtracting 9a to the left side and factoring!
