Question

13. Describe and correct the error in finding the product.

X (x – 5)² = x² – 52
= x2 - 25

Answer 1

Answer:

x=−1.27794

Explanation:

x(x−5)2=x2−52

x3−10x2+25x=x2−52

Step 1: Subtract x^2-52 from both sides.

x3−10x2+25x−(x2−52)=x2−52−(x2−52)

x3−11x2+25x+52=0

Step 2: Use cubic formula.

x=−1.27794
