Can anyone slove these questions from the chapter polynomials? ​

Answer 1

Step-by-step explanation:

★ In second question method is same as Q1. but u apply different formula, which is!!

(a - b)² = a² - 2ab + b²

★ In third question!!

applying formula

--› (a + b)² = a² + 2ab + b²

(x + y)² = x² + 2xy + y²

where, x + y = 12 and xy = 32

(12)² = x² + y² + 2(32)

144 - 64 = x² + y²

x² + y² = 80
