Step-by-step explanation:
Make x the subject of the formula a(x-b)=a^2+bx
1 answer:
Answer:
x =
Step-by-step explanation:
Step 1: Write out formula
a(x - b) = a² + bx
Step 2: Distribute
ax - ab = a² + bx
Step 3: Add <em>ab</em> to both sides
ax = a² + bx + ab
Step 4: Subtract <em>bx</em> on both sides
ax - bx = a² + ab
Step 5: Factor
x(a - b) = a² + ab
Step 6: Divide (a - b) on both sides
x =
Step 7: Factor
x =
And we have our final answer!
