Question

factorise 9 x 2 - 16y2​

Answer 1

GivEn:

• 9 × 2 - 16y²

To find:

• Factorisation of 9 × 2 - 16y².

Solution:

☯ The main aim to Factorise the equation is to find factors.

★ According to the Question:

9x² - 16y²

➯ 3(3x) - 4(4)y²

➯ (3x)² - (4y)²

➯ (3x + 4y)(3x - 4y)

Thus, Through the factorization of 9 × 2 - 16y² the factors obtained are (3x + 4y)(3x - 4y).

⠀━━━━━━━━━━━━━━━━━━━━━━━

Now, let's verify this,

➯ (3 + 4y)(3 - 4y)

➯ 3x × 3x - 4y × 4y

➯ 9x² - 16y²

Hence, Verified!
