The answer is 4a^2.

The GCF is 5b. 5b squared is 25b or (5 x 5) x b 15b is (3 x 5) x b Therefore; 5 x b in each or 5b is GCF

Since you cannot multiply x by a, in the answer you get ax. 2a * 3x = 6ax

x2=(4a)(a) x=√4a2 x=2a The geometric mean of a and 4a is 2a

-b/2a. i think.To show this, consider this equation:y = ax² + bx + cFactor out the a:y = a(x² + bx/a + c/a)Then, complete the squares to get:y = a(x² + bx/a + (b/(2a))² + c/a - (b/(2a))²)= a((x + (b/2a))² + c/a - (b/(2a))²)= a(x + (b/2a))² + c - b/(4a)By the vertex form:y = a(x - h)² + k where x = h is the axis of symmetry.So the general axis of symmetry for the quadratic equation is x = -b/(2a).

2a - a = a
