How do you factor 16a2 4b2?
Assuming the missing sign is "minus" then you have the difference between two squares. This is solved as (x + y)(x - y). In your example x = 4a and y = 2b so the factorisation is (4a + 2b)(4a - 2b) or more completely: (4)(2a + b)(2a - b).
Suppose x and y are odd prove xy is odd?
Write x and y in terms of integers, which we call a and b. For some integer, x = 2a + 1 y = 2b + 1 Multiplying them, you get: xy = (2a+1)(2b+1) = 4ab + 2a + 2b + 1 Since the first terms are even, adding one makes the final result odd.
How do you factorise 4ab?
2a(2b) Would Give You The Answer 4ab. 2x2 = 4 And a x b = ab.
What is the value of 2 times A times by 2 times B times by 5 times A times B minus 4 if A-4 and B5?
A=-4 b=5 2a=-8 2b=10 5ab=-100 2a x 2b x 5ab= -8000
What is the answer of factoring by grouping terms of ax plus 2a plus bx plus 2b?
(x + 2)(a + b)
How do you proof angle in the same segment are equal?
this can be proved by drawing the given circlenow x=2a and x=2b (angle at the centre is double the angle at any point on the circumference.therefore. 2a=2bhence. a=bas asked. this theorem is proved..
Which is a factor of 6a2 plus 5ab - 6b2?
Considering the minus sign between 5ab and 6b2 then we have the polynomial as 6a2 + 5ab - 6b2. The polynomial is a quadratic polynomial.Steps to factorize a quadratic polynomial:1 - Multiply first term by third term. 6a2 x (-6b2) = -36a2b22 - If possible break the second term into two terms such that they multiple to -36a2b2. If not then it is factorized by Sridharacharya's formula.5ab can be broken as 9ab + (-4ab).These two terms multiply to give -36a2b2.So we can write 6a2 + 5ab - 6b2 = 6a2 + 9ab + (-4ab) - 6b2.6a2 + 9ab - 4ab - 6b2 = 3a(2a + 3b) - 2b(2a + 3b) = (2a + 3b)(3a - 2b).So the factors are (2a + 3b) and (3a - 2b).
Simplify 5a plus 4b - 3a?
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
How do you solve 2a to the power of 8b-5 if a to the power of 2b equals 5?
If you mean 2a8b - 5 = x and a2b = 5, then: 2(54) - 5 = x x = 1350 - 5 x = 1345
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 x plus 2a?
x + 2a
The perimeter of a rectangle is 100cm what could be its area?
This is solved by simultaneous equations. Perimeter = 2a + 2b = 100 where a and b are lengths of sides Area = a x b Rearranging the perimeter equation: 2a = 100 - 2b, a = 50 - b Putting this equation into the area equation: Area = (50 - b) x b = 50b - b x b Find the minimum/maximum by differentiating and setting to 0. Area' = 50 - 2b = 0, 2b = 50, b = 25 Area = 625cm sqare. when the length tends to 50, the area tends to 0. So the area can be anything from 0 to 625 cm
