The answer depends on the sequence of operations, which is not specified in the question. E.g. 8 plus (4 squared) is not the same statement as (8 plus 4) squared.When working with parentheses in mathematics, you work what is inside the parenthesis first. In this case are were no parentheses.Strictly following the question, the statement is {[8 + (4)2 ] /8} x 4 = (8+16)x2 = 48.If the (8 plus 4) is squared, the answer is 72.
First you should combine equal terms. For example, 2x2 and -4x2 can be combined as -2x2. Then you can use the quadratic formula.Additonal Answer:-2x2+5x+3-4x2+22 = 0Collect like terms: -2x2+5x+25 = 0Divide al terms by -1: 2x2-5x-25 = 0Factorise: (2x+5)(x-5) = 0Solutions are: x = -5/2 or x = 5

1^2 + 1^2 + 1^2 + 1^2 + 1^2 + 1^2 = 1 + 1 + 1 + 1 + 1 + 1 = 5

Since the problem has 4 terms, first you factor x cubed plus 9x squared, then you factor 2x plus 18. So when you factor the first two term, you would get x sqaured (x plus 9). Then when you factor the last two terms and you get 2 (x plus 9). Ypure final answer would be (x squared plus 2)(x plus 9)
Not in rational terms.
There are no like terms here.
9, 17, 25, 33, 41
it e squard plus c squared
Factor as : (x+9)(x+10) using the first terms ( x terms) multiply to x2; the last terms multiply to 90; the sum of 9x + 10 x = 19x
