SUMMARY

The equation 2x^2 − 12x + p = q(x − r)^2 + 10 requires finding the values of p, q, and r that satisfy it for all x. The correct values are q = 2, r = 3, and p = 28, as established by comparing corresponding coefficients of the polynomial. The transformation of 2x^2 − 12x into the vertex form 2(x-3)^2 is crucial for accurate coefficient comparison. Understanding this method is essential for solving polynomial equations effectively.

2x^2 − 12x + p = q(x − r)^2 + 10 for all values of x find p q and r

i've got

2(x-3)^2 + p = Q(x-r)^2 + 10

so q = 2 r = 3 and p = 10?

now the answers say that Q = 2 r = 3 and p = 28?

can someone explain how to properly go about doing this equation.

2x^2 − 12x is not the same as 2(x-3)^2
 
If a polynomial equation is true for all values of x, then "corresponding coefficients"- that is, coefficients multiplying the same powers of x on opposite sides of the equation- must be the same: multiply the square on the right and compare "corresponding coefficients".

k I've done it now, thx
