Answer 1

Answer:

(p-5)²

Step-by-step explanation:

You need to find all the factors of 25: 5 and 5. Then write an equation that includes that... p+5. Multiply (p+5) times (p+5). You get p²+10p+25. That's not the answer. So make it (p-5) times (p-5). You get p²-10+25. That's correct. (p-5)×(p-5) is the same as (p-5)².

Answer 2

Given

Factories it

p² - 10p + 25

Solution

→ p² - 10p + 25

★ Solve this by splitting middle term

→ p² - 5p - 5p + 25

→ p(p - 5) - 5(p - 5)

→ (p - 5)(p - 5)

Some identities

• (a + b)² = a² + b² + 2ab
• (a - b)² = a² + b² - 2ab
• a² - b² = (a + b)(a - b)
• a³ + b³ = (a + b)(a² - ab + b²)
• a³ - b³ = (a - b)(a² + ab + b²)
