Answer: The answer to this question is (2a-5)(2a+5)
Step-by-step explanation:
- Because first, you have to write the quadratic equation 4a^2-25 in exponential form
- Then, you calculate the product by multiplying the terms with equal exponents by multiplying their bases
(2a)^2-5^2
- And then last but not least, using a^2-b^2=(a-b)(a+b), factor the expression
(2a-5)(2a+5) and then there's your answer and your explanation!!!!!
-6a - 4a + 7a = -10a + 7a = -3a, that isn't 5a;
b. False
Answer:
Yes
Step-by-step explanation:
The standard form for a quadratic equation in the US has the terms in decreasing order by power on the left of the equal sign, and the right side zero. Preferably, the leading coefficient is positive. This might also be called "general form." Elsewhere, the "standard form" may be different.
