Answer 1

Answer:

Find the products:

(a) (3x + 4)(7x - 9)

(b) (x² + y)(x² + x)

(c) (3a²+ b)(2a² + 4b²)

(d) (3x² - y²)(2x² + 3y²)

(e) (5x²- 2y²)(2x² – 5y²

(f) (x⁴- y⁴)(x² - y²)

give me answer of these all questions

Answer 2

Given :-

• (a) (3x + 4)(7x - 9)
• (b) (x² + y)(x² + x)
• (c) (3a² + b)(2a² + 4b²)
• (d) (3x² - y²)(2x² + 3y²)
• (e) (5x²- 2y²)(2x² – 5y²
• (f) (x⁴- y⁴)(x² - y²)

To Find :-

• Find the products ?

Solution :-

• (3x + 4)(7x - 9)

➻ 21x² - 27x + 28x - 36

➻ 21x² + x - 36

• (x² + y)(x² + x)

➻ x⁴ + x²y + x²y + xy

➻ x⁴ + 2x²y + xy

• (3a² + b)(2a² + 4b²)

➻ 6a⁴ + 12a²b² + 2a² + b + 12a²b²

• (3x² - y²)(2x² + 3y²)

➻ 6x⁴ + 9x²y² - 2x²y - 3y⁴

➻ 6x⁴ + 2x²y² - 3y⁴

• (5x²- 2y²)(2x² – 5y²

➻ 10x⁴ - 25x²y² - 2x²y² + 10y⁴

➻ 10x² + 27x²y² + 10y⁴

• (x⁴- y⁴)(x² - y²)

➻ x⁴ - x⁴y² - x²y⁴ + y⁸
