Question

Find the Quadratic polynomial for the zeros. 2 and 5​

Answer 1

Answer:

k(x^2-7x+10)

Step-by-step explanation:

using relationship between zeroes and coefficients.. coefficient of x should be minus of sum of zeroes and the constant term should be positive of the product if zeroes.. it's always better to add a k in front of the equation in bracket to give room for any further possible multiple of coefficients for x squared...

Answer 2

Answer:

$2and - 5 \\ sum \: of = \alpha + \beta \\ = 2 + ( - 5) \\ 2 - 5 \\ = - produtct \: of \: 3 = \alpha \beta \\ = 2 \times 5 \\ = - 10 \\ = x { }^{2} - (a + b)x = \alpha \beta \\ x {}^{2} - ( - 3)x + ( - 10) \\ = x {}^{2} + 3x - 10$

I hope the answer may correct
