Question

Pls solve this question

Answer 1

By using completing the square method we have two values of x .

Answer 2

Answer:

given QE=x^2+4x-1412

x=(-b±√b^2-4ac)/2a

here b=4,a=1,c=-1412

∴(-4±√(-4)^2-4*1*-1412)/2*1

=(-4±√16+5648)/2

(-4±√5664)/2

(-4±4√354)/2

(-4+4√354)/2       or       (-4-4√354)/2

-2+2√354              or     -2-2√354
