-22x minus x equals -23x since they are both like terms and so can be combined into one term.
To determine if ( 22x - 20 ) equals (-440), you can set up the equation: ( 22x - 20 = -440 ). Adding 20 to both sides gives ( 22x = -420 ). Dividing both sides by 22 results in ( x = -\frac{420}{22} ), which simplifies to ( x = -\frac{210}{11} ) or approximately -19.09. Therefore, ( 22x - 20 ) does equal (-440) for this value of ( x ).

It is a quadratic equation and the values of x are: -1/2 and 6
It is an equation and the value of x is 7/19
x3+3x2-22x-90 divided by x-5 equals x2+8x+18 For the answer to be correct then the quotient multiplied by the divisor must be equal to the dividend. Hence:- (x-5)*(x2+8x+18) Multiplying out the brackets term by term: x3-5x2+8x2-40x+18x-90 Collecting like terms in descending order: x3+3x2-22x-90 So the answer is correct.
-3x2 + 22x = 0 You start by dividing both sides by x: ∴ -3x + 22 = 0 Then rearrange to solve for x: ∴3x = 22 ∴ x = 7 + 1/3
P = Cx 'P' = the product 'C' = any integer
3x2 + 22x + 7 = 3x2 +21x + x + 7 = 3x(x + 7) + (x + 7) = (x + 7)(3x + 1)
