4x2-42x+110 = (2x-10)(2x-11) when factored
Length plus height plus width.
10,000 square feet = 1,111.1 square yards.
U turn a square into four squares by making a plus sign
The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.
(x-12)2 using perfect square
The discriminant for the quadratic is b2-4ac = 302 - 4*4*45 = 900 - 720 = 180 Since 180 is not a perfect square, the roots of the equation are irrational and it is far from straightforward to solve such an equation by factoring.
The given quadratic expression can not be factored as a perfect square.
square the first term, plus twice the product of the first and the secon, then square the second.
No.
No, consider 16 + 25 ...
(x+8)^2=105
No
false!
121
yes
49x2 - 56x + 16 = (7x - 4)2 so yes, it can be a perfect square.
