WebThis is then the final solution: x=3 or x=5. We can check these answers by subsitituting these values for x back into the equation to ensure that we get the correct result. For x=3 the equation becomes (3 * 3) - (8 * 3) +15 = 9 - 24 + 15 = 0 which is correct. For x=5 the equation becomes (5 5) - (8 5) + 15 = 25 - 40 +15 = 0 which also solves ...

Step-by-step explanation: Sana po makatulong . 15. 3. x2 - 10x + 25 = 0 Answer ... WebWe can refer to the expression x2 – 8x + 15 as y i.e. y = x2 – 8x + 15. Now what will be the numerical value of y? Obviously the value of y also keeps changing as the value of x changes i.e. the numerical value of y depends on the value assumed by x. If x = –2, y = 35, if x = 0, y = 15 and if x = 2, y = 3.
WebExample 1: Given x 2 + 5x + 6 = 0. ( x + 3) ( x + 2) = 0 (factoring the polynomial) ( x + 3) = 0 OR ( x + 2) = 0. Thus x = −3, Or x = −2. The example above shows that it is indeed easy to solve quadratics by factoring method. However, the method only works for the most basic equations. Ideally the method will only work on quadratics with ... Web0. 10x10=100-4x1x25=-100. 14. x2 + 8x +12 = 0 X2-225 =0 x2 + 10x+25=0 x2 - 81 = 0 x2 -5x +6=0.
