Question

Find the value of x 225x^2 -600=3000​

Answer 1

Step-by-step explanation:

$225 {x}^{2} - 600 = 3000 \\ 225 {x}^{2} = 3000 + 600 \\ 225 {x}^{2} = 3600 \\ {x}^{2} = \frac{3600}{225} \\ {x}^{2} = 16 \\ x = \sqrt{16} \\ x = 4$

verification

(225 × 4²) - 600

= (225 × 16) - 600

= 3600 - 600

= 3000
