How do you factor the perfect trinomial?
Do you mean some thing like 4x2 - 28xy + 49y2 ? notice 4x2 = (2x)2 and 49y2 = either (7y)2 or (-7y)2 (1st and last terms must be squares) and the middle term is 2(2x)(-7y) (2 times sq root of 1st times sq root of last) Once the pattern is recognized: (sq root 1st + sqroot 2nd)2 or (sq root 1st - sqroot 2nd)2 depending on if middle term is positive or negative. So, back to my example: 4x2 - 28xy + 49y2 = (2x - 7y)2 because middle is negative. Simpler example factor x2 + 6x + 9. 1st and last are both squares sq root of 9 = 3 3 times 2 = 6 that fits the middle so x2 + 6x + 9 = (x + 3)2

This is a difference of two sqaures. 49y2 - z2 = (7y - z)(7y + z)
What is the factor ofsixteen x squared-fortynine y squared?
(4x - 7y)(4x + 7y)
How do you solve for y in 14x equals 7y plus 28?
14x = 7y+28 -7y = -14x+28 Divide all terms by -7 to find the value of y: y = 2x-4 which is now in slope intercept form
What is the answer to -7y equals 28?
y=-4
7(y-6)=28?
7y-42=28 ==> 7y=42+28 => y=70/7. => 10
What is a common factor of 7y plus 105?
The GCF is 7.
When completely factored 4 16x 28y equals?
To factor the expression (4 + 16x + 28y), we first observe that the coefficients 4, 16, and 28 have a common factor of 4. Factoring out 4 gives us: [ 4(1 + 4x + 7y) ] Thus, the completely factored form of the expression is (4(1 + 4x + 7y)).
