(x² + 16x)² = 17²

√x² + 16x)²  =  √17²
(x²  +  16x)   = (+-)17
1st equation: x²+16x-17 = 0
2nd equation:x²+16x+17 =0
Let's solve these 2 quadratic equation:
1st equation x' =1 & x" = - 17
2nd equation x'= (-8+√47) & x" =(-8-√47)

Solve x:<br> 6 - x/2 = 10<br> --Please Help! Maths Homework Due In For Monday! Xx
ratelena [41]

6 - \frac{x}{2}= 10  Subtract 6 on both sides

6-\frac{x}{2}-6=10-6

-\frac{x}{2}= 4

Multiply -2 on both sides to get "x" by itself

-\frac{x}{2} (-2) = 4(-2)


x = -8

P.S:I am a 6th graders who doesn't really understand negatives, but i tried my best and got this answer.
