What is the answer to x2-9x plus 21 equals 0?
This quadratic equation has no solutions because its discriminant is less than zero.
What is the value of n in this equation 2n plus 1 equals 21?
2(10)+1
Write an equation for n plus 13 equals 21?
n + 13 = 21. n = 21 - 13
Can you solve 21 plus 6x plus 1?
It can be simplified to: 22+6x or 6x+22But that's only a different, neater way to write it. It's not a 'solution', because"21 + 6x + 1" is not an equation or a question. It's just an expression that standsfor a number. The value of the number depends on the value of 'x'.
What is 25x plus 3x plus 2l equals 32 plus 5l plus 9?
25x+3x+21 = 32+51+9 Collect all like terms together and notice the change from +21 to -21, this is done in order to keep the equation in balance. 25x+3X = 32+51+9-21 28x = 71 Divide both sides of the equation by 28 to find the value of x: x = 71/28 or 2 and 15/28 x = 2.535714286 as a decimal
