⚠️⚠️⚠️⚠️ #50 Points

Please Factorise the Following Equations

1.) (100-9x²)
2.) (49x²-1/4)​

Answer 1

$1. \: {10}^{2} - {3x}^{2} \\ = (10 + 3x)(10 - 3x) \\ \\ 2. \: {7x}^{2} - {( \frac{1}{2} )}^{2} \\ = (7x + \frac{1}{2} )(7x - \frac{1}{2} )$

Answer 2

Answer:

Step-by-step explanation:

1. (100-9x^2)=(10^2-(3x)^2)=(10-3x)(10+3x)

2. (49x^2-1/4)=((7x)^2-(1/2)^2)=(7x-1/2)(7x+1/2)

Use, (a^2-b^2)=(a+b)(a-b)
