Question

polynomial expression of x²-7x=10​

Answer 1

Step-by-step explanation:

x2 - 7x+10 =0

x2 - 2x -5x +10 =0

x ( x +2) 5(x +2 ) = 0

(x+5) (x+2)

zero of the polynomial:

(x+5) =0

x = -5

(x+2)=0

x=-2

1. verification :
2. $\alpha + \beta = - b \div a$now let alpha = -5 and bita =-2

-5+(-2)=7

-(-7)/1=7

$\alpha \beta = \frac{c}{a}$

-5*-2 =10

10/1 =10

Answer 2

Answer:

D would be x^2 + 7x + 10. The answer choice that matches the question is C. (x - 2)(x - 5). Hope this helps!
