Question

What value of c makes the polynomial below a perfect square? x^2+10x+c    C=?

jim_thompson5910 · Answer

the x coefficient is 10

take half of this to get 10/2 = 5

then square this to get 5^2 = 25

jim_thompson5910 · Answer

so c = 25

what about : what value of b makes the polynomial below a perfect square? x^2+bx+16 B=??

jim_thompson5910 · Answer

go backwards from what I did

jim_thompson5910 · Answer

you first take the square root of 16 to get sqrt(16) = 4

then you double this to get 4*2 = 8

that means b = 8
