The method of completing the squares method will be used for the next step. The next step would be ( x+ (b/2a) )^2 = -c/a + b^2/(4a^2)
What is the expansion of square of sum of two terms?Suppose that two terms are 'a' and 'b'.
Then, their sum's square is expanded as:
[tex](a+b)^2 = a^2 + 2ab + b^2[/tex]
For this case, we're given the quadratic equation with its 4 steps of solution as:
[tex]ax^2 + bx + c = 0\\\\\dfrac{ax^2}{a} + \dfrac{bx}{a} + \dfrac{c}{a} = 0\\\\x^2 + \dfrac{bx}{a} + \dfrac{c}{a} = 0\\\\x^2 + \dfrac{bx}{a} = -\dfrac{c}{a}\\\\x^2 + \dfrac{bx}{a} + \dfrac{b^2}{4a^2} = -\dfrac{c}{a} + \dfrac{b^2}{4a^2}[/tex]
We've to proceed to the next step.
In the left hand side, we can use the formula [tex](a+b)^2 = a^2 + 2ab + b^2[/tex], where [tex]\rm a \: is \: x^2, and \: b \: is \: \dfrac{b}{2a}[/tex]
Thus, we have:
[tex]x^2 + \dfrac{bx}{a} + \dfrac{b^2}{4a^2} = x^2 + 2 \times x \times \dfrac{b}{2a} + \left(\dfrac{b}{2a} \right)^2 = \left( x + \dfrac{b}{2a} \right)^2[/tex]
We expressed the left sided expression in this form so that the variable 'x' (which is assuminly the only variable in the equation, whose value is to be known) gets packed into single container and not spread throughout with different powers.
Now, we can use square root and then subtraction and division of some terms which will make 'x' stay on one side of the equation, and rest of the constants on other side, as the value of 'x' for which the considered equation [tex]ax^2 + bx + c = 0[/tex] is correct.
The next step of the solution, therefore, is:
[tex]\left( x + \dfrac{b}{2a} \right)^2 = \dfrac{-c}{a} + \dfrac{b^2}{4a^2}[/tex]

"The Martin family's truck gets an average of 25 miles per gallon of fuel. Predict how many miles they will be able to get from 7 gallons of fuel by using equivalent rates." (Explain with fractions/ equivalent rate in detail pls)
Answer:
175 miles
Step-by-step explanation:
Average of 25 miles per gallon of fuel
Miles : gallons = 25 : 1
Predict how many miles they will be able to get from 7 gallons of fuel by using equivalent rates
Let x = number miles
Miles : gallons = x : 7
To find x
25 : 1 = x : 7
25/1 = x/7
Cross product
25*7 = 1*x
175 = x
x = 175 miles
Number miles = 175

y = mx + b -2 = 3(4) + b -2 = 12 + b -14 = b; the y-intercept is -14 What is wrong with this answer?
Answer:
There is nothing wrong with the answer obtained
Step-by-step explanation:
Given the equation :
Y = mx + b
-2 = 3(4) + b
-2 = 12 + b
-14 = b
The correct calculation :
Y = mx + b
-2 = 3(4) + b
-2 = 12 + b
Subtract 12 from both sides
-2 - 12 = 12 + b - 12
-14 = b
Based on the details of the question given, the intercept, b is - 14 ;
Hence, there is nothing wrong with the answer
