Find the Mistake

100

Determine Kelsey's error and correct it:

4x² + 5x² = 9x⁴

Kelsey incorrectly added the exponents. The correction should be:

4x² + 5x² = 9x²

200

Determine Enrique's mistake and correct it: 

4x³ + 5x³ + x²= 20x³ + x²

Enrique multiplied the coefficients instead of adding them. It should be: 

4x³ + 5x³ + x²= 9x³ + x²

300

Determine Rocio's mistake and correct it:

(x+3)² = x² + 9

Rocio squared each term instead of squaring the whole polynomial. It should be: 

(x+3)2 = (x+3)(x+3) = x² +6x +9

400

Determine Irene's mistake and correct it:

2x(x-4) = 3x²-6x

Irene is adding the coefficients instead of multiplying them. It should be:

2x(x-4) = 2x²-8x

500

Determine Jose's error and correct it:

(2x+5)² = 4x²+25

Jose did not write (2x+5) twice:

(2x+5)² = (2x+5)(2x+5)

=4x²+20x+25
