2013年8月8日 · The easiest way to factor a quadratic equation ax 2 + b x + c is to use the quadratic formula. What you are doing is assuming the equation is set equal to zero and then solving for the different values of x that would make this a true statement.

2014年4月27日 · Because both equations are true are answers is correct and the two numbers are -16 and -14. If you have problems remembering the adding a negative and subtracting a negative then just remember the multiplying rule that any two signs alike multiplied are positive and any two signs not alike that are multiplied are negative and then just imagine an imaginary …

(x-2)(x-1)=30,x^2-2x-x+2=30,x^2-3x+2-30=0since x^2-3x-28=0 by factorization x^2+4x-7x-30=0,x(x+4)-7(x+4)=0 thrfr (x-7)(x+4)=0hence x=7 However, at least one of these solutions fails to work when substituted back into the original equation.

2014年4月14日 · how to factor x squared + 13 +30 - 2x squared + 13x +30 - 6xsquared-13x+30-the primeter of a triangular park is 16x+5 if one side is 12+5 another is 2x-1 find the missing side.

2020年2月7日 · A quadratic function is a second-degree polynomial function that looks like f(x) = ax 2 + bx + c. Y-intercept means the function crosses the Y-axis at that point so the X value will be zero at that point, so if we replace x with zero in our equation and y or f(x) with 7, our c value in fact as the Y-intercept will be 7: c=7

2015年2月21日 · The area of the triangle is 5cm^2. find the base, to the nearest tenth. Answers · 1 One pool is 4m wide, another is 6m longer than the first. the width of the 2nd pool is equal to the length of the first, find the are of pool 2

The x coordinate of the vertex is 30. The y coordinate of the vertex is k, which is defined as k = f(h) For this problem, k = f(30) In other words, we plug in x = 30 to find the y coordinate of the vertex. Replace every x with 30; use PEMDAS to simplify We see that k = 2500, meaning the y coordinate of the vertex is 2500. The vertex is at (h,k ...

2022年2月15日 · The product of two positive real numbers x and y is 30. x*y = 30. Find the minimum possible value of their sum. Sum = S = x + y *solve the first equation for either x or y then substitute into the second equation. y = 30 / x. S = x + (30/x) *Derive S, then set S' equal to zero. S' = 1 - 30/x^2. 0 = 1 - 30/x^2 *Solve for x. 30/x^2=1. 30=x^2. x ...

2019年8月15日 · Use the quadratic formula with a=1, b=11 and c= -30, to find 2 possible values of B solving the equation. (-b =/- sqrt(b 2 - 4ac))/2a. Plug in values of a, b and c to get (-11 +/- sqrt(121 - (-120)))/2 ==> (-11 +/- sqrt(241))/2 = 2.262 and -13.262. Note that -13.262 + 2.262 = -11 and -13.262 * 2.262 = -29.9998 ~ -30 (the product is not -30 due ...
