Question

use factoring to solve the quadratic equation: x(x-8)=-16(x+1)

Answer 1

x^2+8x+16=0
=> (x+4)(x+4)=0
so, x=-4,-4

Answer 2

so, with these problems, you will always have to put it in ( )( ) form?

Answer 3

yes, factorise and keep 0 to the rhs

Answer 4

okay thanks =] so with x(x+22)=11(4x-11) it would be (x+11)(x-2)=0 ?
