(4-x)^2-2x pls help to solve it |
|
Answer» Given : (4 - x)² - 2X• Idenitity : (a - b)² = a² + b² - 2ab Here, a = 4, b = x→ (4)² + (x)² - 2(4)(x) - 2x→ 16 + x² - 8x - 2x→ 16 + x² - 10xHence, the answer is x² - 10X + 16.If you want the above equation to be further SOLVED, then using Middle TERM Factorisation. → x² - 8x - 2x + 16→ x(x - 8) - 2(x - 8)→ (x - 2)(x - 8)Hence, the final answer is (x - 2)(x - 8). |
