x2+7x-18 = (x+9)(x-2) when factored
The expression 7X + 8 represents a mathematical operation where the variable X is multiplied by 7 and then 8 is added to the result. The expression cannot be simplified further without knowing the specific value of X. If X is a known value, you can substitute it into the expression to find the numerical result.
X = 10 7x-5=65 +5 +5 7x=70 /7 /7 So X=10
Oh, what a happy little math problem we have here. To factorise x squared plus 7x, we can first look for a common factor, which in this case is x. So, we can factor out an x to get x(x + 7). And just like that, we've created a lovely little factorised expression.
7x2 + 7x - 14 = 7(x2 + x - 2) = 7(x + 2)(x - 1)
