Question

Find the quadratic polynomial whose one zero is 7 and product of
zeroes is 35.

Answer 1

Answer:

$a \: = 7$

$ab = 35$

$7 \times b = 35$

$b = 5$

$quadratic \: polynomial$

${x}^{2} - \: ( \frac{b}{a} )x + \frac{c}{a} = 0$

${x}^{2} - \frac{5}{7}x + 35 = 0$

$7 {x}^{2} - 5x + 245 = 0$
