Whay maked this statement true ?7-^2=?
2 answers:
Remember the following:
-ve * -ve = +ve
-ve * +ve = -ve
x² = x * x
x⁻² =
Now, for the given:
1- If the given equation is -(7)², then:
-(7)² = - (7*7) = -49
Therefore,, -49 would make this statement true.
2- If the given equation is (-7)², then:
(-7)² = (-7) * (-7) = 49
Therefore, 49 would make this statement true
3- If the given equation is 7⁻², then:
7⁻² =
Therefore,
would make the statement true.
Hope this helps :)

Answer:
Given Polynomial:
Factors of Coefficient of terms
80 = 5 × 16
32 = 2 × 16
48 = 3 × 16
Common factor of the coefficient of all term is 16.
Each term contain variable. So the Minimum power of b is common from all terms.
Common from all variable part comes b².
So, Common factor of the polynomial = 16b²
⇒ 16b² ( 5b² ) - 16b² ( 2c³ ) + 16b² ( 3b²c )
⇒ 16b² ( 5b² - 2c³ + 3b²c )
Therefore, Statements that are true about David's word are:
The GCF of the coefficients is correct.
The variable c is not common to all terms, so a power of c should not have been factored out.
In step 6, David applied the distributive property
