x2 + 4x - 96 = (x - 8)(x + 12).
It is -4x -96.
This is an equation known as a quadratic equation.x2-4x-96=0x2-4x=96-B +-SQUARE ROOT OF B-4AC OVER 2AA=1B=-4C=-96-4-4(1)(-96)=SQUARE ROOTOF 380ANSWER : 4-+ SQUARE ROOTOF 380 OVER 2Improved Answer:-x2-4x-96 = 0(x-12)(x+8) = 0x = 12 or x = -8
It is -4x -96.
4 x 30 = 120
4x24=96 20 x 4 = 80 4 x 4 = 16 80 + 16 = 96
x2 - 4x - 96 = 0 (x - 12)(x + 8) = 0 x = 12, -8 Check it. 144 - 48 - 96 = 0 64 + 32 - 96 = 0 It checks.
(x + 12)(x - 8)
There are 96 heads, so 96 animals. If all were horses, that would be 4 x 96 = 384 legs, but there are only 313 legs, which means there are 384-313 = 71 legs short or 71 cows and 25 horses. Mathematically, let x = horses and y = cows x + y = 96 4x + 3y = 313 multiply first equation by 4: 4x + 4y = 384 4x + 3y = 313 subtract equations y = 71 = cows x = 25 = horses
4x to the sixth can be expanded to (4x * 4x * 4x)(4x * 4x * 4x) or (4x to the third)(4x to the third) the square root of the above would be 4x to the third
4x × 4x = (4x)² = 16x²
16x
