A quadratic equation has the general form
of: <span>
y=ax² + bx + c
It can be converted to the vertex form in order
to determine the vertex of the parabola. It has the standard form of:
y = a(x+h)² - k
This can be done by completing a square. The steps are as follows:
</span><span>y = 3x2 + 9x – 18
</span>y = 3(x2 <span>+ 3x) – 18
</span>y + 27/4= 3(x2 <span>+ 3x+ 9/4) – 18
</span>y = 3(x2 + 3/2)^2 – 99<span>/4
</span>
Therefore, the first step is to group terms with the variable x and factoring out the coefficient of x^2.
Answer:
3 8/9
Step-by-step explanation:
How many times does 18 multiply to 70-
18 * 1 = 18
18 * 2 = 36
18 * 3 = 54
18 * 4 = 72
If we go past 3 times then it goes higher than 70, so 18 goes into 70 3 times.
18 * 3 = 54
70 - 54 = 16
The left over will be the numerator and the denominator stays the same.
Don’t forget to simplify-
16 / 2 = 8
18 / 2 = 9
