Question

10 / (x ^ 2) + 8x + 16; 11/9 * x ^ 2 + 12xy + 4y ^ 2; 12/4 * x ^ 4 + 20x ^ 2 + 25; 13/4 * x ^ 2 - 12xy + 9y ^ 2; 14/25 * x ^ 2 - 20xy + 4y ^ 2; 15/25 * x ^ 2 -

Answer

10, (x + 4); 16, (3x ^ 2 + 2y) ^ 2; (2x - 3y) ^ 2; log(4x ^ 2 + y ^ 2) ^ 2 44 ( ) 14 ( 2g ) 2 ( + 3y ( x 3x

Answer

10, x² + 8x + 16  = x² + 2.x.4 + 4² = (x+4)²  11, 9x² + 12xy + 4y² = (3x)² + 2.3x.2y + (2y)² = (3x+2y)² 12, 4x⁴ + 20x² + 25 = (2x²)² + 2.2x².5 + 5² = (2x² + 5)²  13, 4x² - 12xy +
