# How do you factor 2x^2 - 11x + 5 = 0?
Jun 9, 2016
$\left(2 x - 1\right) \left(x - 5\right) = 0$, which gives the solution as $x = \frac{1}{2}$ or $x = 5$.
#### Explanation:
To factorize $a {x}^{2} + b x + c$, one should split the middle term $b$ in two parts, whose product is $a c$
Hence in $2 {x}^{2} - 11 x + 5... |

A fraction is a number expressed as the quotient of two mathematical expressions, often integers. Fractions come in the form $\frac{a}{b}$ , where $a$ is called the numerator and $b$ is called the denominator.
Sometimes the word "fraction" means the quotient of two integers. Under this definiti... |

# Quadratics in the xb Plane
### Sean Johnston
When looking at quadratic equations, we often apply the quadratic formula to the standard form, a+ bx + c = 0, to find the roots. In this assignment, we will explore the roots of quadratics with particular values of a and c. We will first look at the case when a = 1 and ... |

Q.1 Express the trigonometric ratios sin A, sec A and tan A in terms of cot A.
Sol. Consider a $\Delta ABC$, in which $\angle B = 90^\circ$.
For $\angle A$, we have
Base = AB, Perp = BC
and Hyp = AC
Therefore, $\cot A = {{Base} ... |

Solving a quadratic equation (factorization method)
In polynomials, we studied that a polynomial of degree 1 is called a linear polynomials.
For example: x - 5, 7x, 3 - 2x are linear polynomials which may be monomials or binomials.
A polynomial of degree 2 (two) is called a quadratic polynomial.
For example: 3x², x... |
