What does a equal in 1/2(a-7)=33?​

Mathematics

Dmitriy789 [7]3 years ago

To find a, you need to isolate/get the variable "a" by itself in the equation:

\frac{1}{2} (a-7)=33    Multiply the inverse of 1/2, which is 2, to get rid of the fraction

(2)\frac{1}{2}(a-7)=(2)33

a - 7 = 66      Add 7 on both sides to get "a" by itself

a - 7 + 7 = 66 + 7

a = 73

What number must you add to complete the square x^2+4x=15
Andrew [12]
Since we want it in the form: (x - a)², let's first expand (x - a)² and then equate for the coefficients.

(x - a)² = x² - 2ax + a²
x² + 4x - 15 = x² - 2ax + a²

Now, let's focus on the middle term.
4x = -2ax
4 = -2a
a = -2

Thus, we know that a = -2
Then, we can say (x + 2)² = x² + 4x - 15
x² + 4x + 4 = x² + 4x - 15
Thus, 19 units are needed in order to complete the square to produce:
(x + 2)²
