write a quadratic function whose only zero is 10

Answer 1

Hi Liya,

If you need the FUNCTION and you have ONLY one zero it means:

this function touch x-axis and its equation will be

Y = k ( x - 10 ) ²

we dont know k because there is not another information BUT if you dont write k you wiil loose some part of score.

I hope it is useful,

Minoo

Answer 2

(x-10)(x-10) = 0

x^2 - 20*x + 100 = 0
