Please: Use "^" to denote exponentiation: <span>2x^2 + 8x - 12 = 0
Reduce this by div. every term by 2: </span><span>x^2 + 4x - 6 = 0
Here a=1, b=4 and c = -6. Square half of b, obtaining (4/2)^2 = 4, and add, and then subtract, this 4 to x^2 + 4x - 6:
</span> x^2 + 4x +4 - 4 - 6 = 0. Rewrite the square as (x+2)^2, obtaining new equation
(x+2)^2 = 10. Take the sqrt of both sides: x+2 = plus or minus sqrt(10).
Finally, solve for x: x = -2 plus or minus sqrt(10).
100/40×20.
100/40=2•5
2•5×20=50
the answer is 50

Answer:
<h2><u><em>
False</em></u></h2>
Step-by-step explanation:
Is this true or false:
w(5)=w(-5)
we give the value 1 to w to keep it simple
1 ( 5 ) = 1 (-5 )
5 = -5
<em>It's false</em>
