What number would you add to complete the square for the equation below?

X^2+14x=0

Hi im college teachrr the answer is 7 thank you now good bye

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

)because it's going in order of the math sign
