Excuse if I have this wrong but I’m going to guess that in every question how the 2 is up the m or the other letters that means you are multiplying that number/ letter by its self one more time so I’m not really sure, I’m sorry.

Give the values of a, b, and c needed to write the equation's standard form.(5 + x)(5 - x) = 7A = 1; B = 0; C = -18A = 25; B = 0

Maksim231197 [3]

We need to FOIL that out and then get it into standard form to see what our A, B, and C are. FOILing gives us $25-x^2=7$ . If we move the 7 over by subtraction and set it equal to 0, we have $-x^2+18=y$ . In order to avoid a negative leading coefficient, we can change all the signs to get $x^2-0x-18=0$ so A = 1, B = 0, C = -18, first choice above.

Explain how to determine if the two expressions are equivalent using x = 6 and x = 2.

Nataly_w [17]

Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same.
