2.HCF =12

a×b=1800 (GIVEN)

By formula,

HCF×LCM=a×b

LCM=  \frac{a \times b}{HCF}

LCM=  \frac{1800}{12}

LCM=150

3.Given quadratic polynomial is

3x² - kx + 6

Compare given polynomial with

ax² + bx + c , we get ,

a = 3 , b = - k , c = 6

Sum of zeroes of the polynomial is given by ,

➠  \sf -\dfrac{b}{a}

where ,

b denotes coefficient of x

a denotes coefficient of x²

Given , Sum of zeroes = 3

➠  \sf -\dfrac{b}{a} = 3

➠  \sf -\dfrac{(-k)}{3}=3

➠ - (-k) = 3 (3)

➠   k = 9  \pink{\bigstar}
