What is the X co-ordinate of vertex of parabola where equation is Y is equal to X square + bx + c =\ o

x = -

Step-by-step explanation:

Given a quadratic equation in standard form , that is

y = ax² + bx + c = 0 ; a ≠ 0

Then the x- coordinate of the vertex is

= -

x² + bx + c = 0 ← is in standard form

with a = 1, b = b, thus

= -

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
