What is the greatest common factor of 5b squared and 15b?
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
2a x 2a?
The answer is 4a^2.
What is 2a x a?
2a2
What is 2a x 3x?
Since you cannot multiply x by a, in the answer you get ax. 2a * 3x = 6ax
What is expressions in maths?
A mathematical expression is a mathematical phrase that consist numbers variables and signs of operation example: x(variable) + 5(number)=7 so the value of x is 2 -Kennethn 10 yrs. old :]
What is 5b x -2a?
7
What are 2 equivalent expressions for 5b plus 5b?
5b + 5b = 2 x 5b
What is all the factors of 252980?
There are 48 factors of the form 2a x 5b x 7c x 13d x 139e where a = 0, 1 or 2 and b, c, d and e = 0 or 1.
How do you factorise 4ab plus 2ac?
5 = 1 x 5, 21 = 3 x 7 3 x 5 = 15, 1 x 7 = 7, 15 - 7 = 8 so: (5x + 7)(x - 3)
What is 2a x a?
2a2

2a x 2a?
The answer is 4a^2.
What is x plus 2a?
x + 2a
What is the answer to 2a x 3b?
2a x 3b = 6ab
What is the answer to 2b x 5b?
10b2
What is the axis of symmetry formula?
-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).
What is 2a x 3x?
Since you cannot multiply x by a, in the answer you get ax. 2a * 3x = 6ax
