Completing the square - write in the form (x + p)squared + q

This video is all about completing the square and forms part of the higher level playlist of the same name. I've also added to the playlist on GCSE higher revision.

The question is likely to be around level 4 - 6, and there's usually only a few marks available.

Write in the form a(x + p)squared + q

xsquared - 10x + 1

[rubenbet]

for a second I thought I was learning math from Paul McCartney. You sound a lot like him.

[varaanawaz]

Hey! On 0:46 when you halved the equation why didn't you write 5x..i mean where did the x go?? Plzz reply.. Its really urgent

[Sxyel]

It makes so much more sense now! Thank you!!!

[damn_.]

Thank you so much, i understand it a lot better now!

[mishmalkhan]

u really saved my life, but i don't get how we had to make it in the form +q instead we got -q (which was -24). Is that allowed?

[kozumin]

thanks for this video! really helped me solve my homework

[anthony]

Want so you do if you have a coefficient in front of x^2? Like 3x^2-10x+1

[sarimbaig]

Hey Bud! Can you please explain why you moved the 'squared' from the 'x' to the outside of the bracket?

[Ahrong]

Hi, u just worked out to be +25. How did it turn out to be -25 ?

[BassMSL]

Hey there, when you expand the x -5^2 bracket how do you get (x-5)(x-5), wouldn't it be (x-5)(x+5)?

[abelgloriavihemba]

Solve this 3x^2×3x-6 in the form of a(x+p)^2+q

[marleyjames]

If the form is (x+p)^2 -q instead of making the 25 a negative would it be a positive?

[sharveshbaskaran]

Is (x + p)squared + q as same as (x + m)squared + n @3 minute maths

[Kookakoolio]

Rhank you for your helo but i want to ask what hapoens when the number b4bthe variable is odd and not even

[ruqayaameer]

plz i want u to solve this
x^2+8x
by completing the square in the form (x+a) ^2 +b

[jassimmd]

can this be used in differentiation ??

[MohamedAli-ksqy]

why we need to change the sign of 25 from positive to negative? 1:38
