Question

given that x2+ax+b=(x-7)2-a work out a and b

Answer 1

x^2 + ax + b = 0x^2 + 2x - 14 - a

Answer 2

x^2 + ax + b = 0x^2 + 2x + ( - 14 - a )

Answer 3

(x-7)^2 = x^2 -14x +49
- so than can you continue it ?

Answer 4

ohhhh lol sorry johnny is right.. guys please use the correct notation haha

Answer 5

I assumed it was ()*2

Answer 6

Can u explain the steps please?

Answer 7

x2+ax+b=(x-7)2-a
x^2 + ax + b = x^2 - 14x + 49 - a, right?

Answer 8

Subtract x^2 from both sides:
ax+b = -14x + (49-a)
