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).
Answer:
You can do this on ur own
Step-by-step explanation:
Trust me
It would be,
t= 10w + 25
And to make a graph but in values for w;
w: 1 / 2 / 3 / 4
t: 35/ 45 / 55 / 65
And then you plot the points on the graph.
It’s A trust me I just did it
It would be twice whatever the midsegment equals.
