x = -8 and x = 4.
x2 + 4x - 32 = 0
We can factor this to:
(x + 8) (x - 4) = 0
Therefore:
x + 8 = 0
x = -8
and
x - 4 = 0
x = 4
Thus the two roots of the quadratic equation are -8 & 4.

x+32 = 10 x = 10-32 x = -22
32 + x = 259 + x = 25x = 25 - 9x = 16
x2 (4x4=16) + Y2 (4x4=16) = 32 You normally would leave out the bracketed bits but to simplify the equation. Cheers.
No. It equals 32 feet per second squared, or 32 ft sec-2
1+32+52=41... The brackets go around the first part like this - (1+3)2+52=41 Because... 1+3=4 squared is 16, add that to 5 squared (25) equals 41.
