Yogita Ingle 6 years, 10 months ago

2x - y = 6
Put x = 2 and y = -2
LHS = = 2x - y
= 2(2) - (-2)
= 4 + 2
= 6
= RHS
So, (2,-2) is a solution of 2x - y = 6.

Yogita Ingle 6 years, 10 months ago

We know that a quadratic polynomial when the sum and product of its zeroes are given by
p(x) = K {x² – (sum of the zeroes) x + Product of zeroes},
where K is a constant.
Therefore, required quadratic polynomial p(x) is given by
p(x) = K[x²–(5x)+(6)] = K (x² - 5x+ 6).
