Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x2 – 6 = x

X = 3
x = -2

Make sure to solve for 0 and then find your a, b, and c for the quadratic formula. In this case a = 1, b = -1 and c = -6

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

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.
