The general expression for a quadratic polynomial is: ax2 + bx + cComparing x2 - 4x - 45 with general expression we geta = 1, b = -4 and c = -45Multiplying a and c: ac = -45Now break down b in two numbers in such a way that sum of the numbers is -4 and product is equal to -45, product of a and c.The two numbers are -9 and 5. Since sum of -9 and 5 is -4 and the product is -45.So in place of -4x we can write -9x + 5x.The expression now becomes: x2 - 9x + 5x - 45x(x - 9) + 5(x - 9)(x + 5)(x - 9)So factors are (x + 5) and (x - 9).Note: The middle term is split into two terms so that there are in total four terms in the expression and the product of extreme terms is equal to product of middle terms.
To evaluate 15k when k equals 3, you would substitute the value of k into the expression. Therefore, 15k becomes 15(3), which simplifies to 45. So, when k equals 3, 15k equals 45.
To find the value of y in the expression 15y-4 = 41, you need to isolate y. Start by adding 4 to both sides of the equation to get 15y = 45. Then, divide both sides by 15 to solve for y, which equals 3. Therefore, the value of y in the expression 15y-4 when it equals 41 is 3.
It is a simple (i-e. not quadratic or cubic)equation with several unknown quantities.
