12a2b plus 8a-5a2b plus 2ab - 4ab2 plus 6ab-2a-3ab?
Assuming that non-leading numbers are exponents, the expression becomes12a^2b + 8a - 5a^2b + 2ab - 4ab^2 + 6ab - 2a - 3ab= 7a^2b + 6a + 5ab - 4ab^2= a*(7ab + 6 + 5b - 4b^2)
What does a formula start with?
it usually starts with x=.... ex: for foil method , which is (a+b)2 would be x=a2+2ab+b2
What is a square b square 2ab?
a^2 + b^2 + 2ab = (a + b)^2
Twice the product of a and b?
x=ab
Show a plus b divided 2 equals 2ab divided by a plus b?
b/2=2ab/+b means112.5
What is the expression for a x 2b?
( 2ab ) is.
12a2b plus 8a-5a2b plus 2ab - 4ab2 plus 6ab-2a-3ab?
Assuming that non-leading numbers are exponents, the expression becomes12a^2b + 8a - 5a^2b + 2ab - 4ab^2 + 6ab - 2a - 3ab= 7a^2b + 6a + 5ab - 4ab^2= a*(7ab + 6 + 5b - 4b^2)
What is Special Case Product of Binomial?
Some special cases that are relevant in practice are: (a + b)2 = a2 + 2ab + b2 (a - b)2 = a2 - 2ab + b2 (x + a)(x + b) = x2 + (a+b)x + ab
What is -a x 2 x b-3?
5
What is the simplified form of 4ab2?
The expression is already in its simplest form.
X2 -5kx plus 25 the square of binomial. what is a possible value of k?
k can be 2 or -2. A binomial squared is: (a + b)² = a² + 2ab + b² Given x² - 5kx + 25 = (a + b)² = a² + 2ab + b² we find: a² = x² → a = ±x 2ab = -5kx b² = 25 → b = ±5 If we let a = x, then: 2ab = 2xb = -5kx → 2 × ±5 = -5k → k = ±2 If k = 2 then the binomial is (x - 5)² If k = -2 then the binomial is (x + 5)² To be complete if a = -x, then: If k = 2 then the binomial is (-x + 5)² If k = -2 then the binomial is (-x - 5)² which are the negatives of the binomials being squared.
How do you factor a times a cubed plus 2 times a times b plus b squared?
the answer to factorising (a x a3 + 2ab + b2) would be (a4+2ab+b2)
What is 2ab-2?
2ab-2 = 0
What is 2ab-6bc?
2ab-6bc = -4
What is 2ab when a -2 and b 7?
2ab = 2*(-2)*7 = -28
X equals 2ab plus 7 find x if a equals 3 and b equals 5?
42 72
What does a formula start with?
