I assume you mean a polynomial of degree 4. In general, a polynomial of degree "n" can be separated into "n" linear factors. As a result, a polynomial of degree "n" has exactly "n" solutions - unless two or more of the factors are repeated; in which case the corresponding solution is said to be a multiple solution.As an example:(x - 2)(x - 5) = 0has two solutions, namely 2 and 5; while(x - 3)(x… Read More

The zero of a function is a point where the function evaluates to zero. If you express "y" as a function of "x", i.e. y = f(x), then for a zero of the function, the y-coordinate is 0. In other words, the corresponding point is on the x-axis. Read More

That's not an inequality; an inequality needs a "greater than" or a "less than" sign. Those must have gotten lost when you typed the title. Anyway, basically you are supposed to replace the numbers one by one in the inequality, do the calculations, and see whether the resulting statement is true or not. Read More

You can write a proportionality (between "x" and "y") as:y = kxwhere x is some constant.For x = 0, y is also equal to zero, no matter what the value of k. Thus, the point (0, 0) - i.e., the origin - is part of the solution set. Read More

The main difference is that if you multiply or divide by a negative number, you need to simultaneously invert the inequality - for example, a less-than sign becomes a greater-than sign. Example:-2x < 15Multiplying by -1/2 (equivalent to dividing by -2):x > 7.5 Read More

1 Let the height be x+1.75 and the base be x2 1837.5 sq mm is the same as 18.375 sq cm3 0.5*(x+1.75)*x = 18.375 => x2+1.75x-36.75 = 04 Using the quadratic equation gives x a positive value of 5.255 Therefore: height = 7 cm and base = 5.25 cm6 Using Pythagoras: hypotenuse = 8.75 cm7 Perimeter: 8.75+7+5.25 = 21 cm Read More

The area of similar figures is proportional to the square of any linear measurement. (And all linear measurements are directly proportional.) Thus, if the ratio of the perimeters is 5/4, the ratios of the lengths of sides is also 5/4. The ratio of the areas, on the other hand, is (5/4)2, so you can simply multiply the area of the smaller square by this factor. Read More

Cutting the equilateral triangle in half results in two right triangles each with a base of length x/2, and angles of 30, 60, and 90 degrees. Using the lengths of sides of a 30-60-90 triangle it can be found that the height is (x/2)√(3), which is the same as the height of the equilateral triangle. So the height of the equilateral triangle is x√(3) / 2. Read More

It follows from the multiplication property of equality. Dividing both sides of an equation by the same number (not by zero, of course) is the same as multiply both sides of the equation by the number's reciprocal. For example, dividing both sides of an equation by 2 is the same as multiplying both sides by 0.5. Read More
