7C MINUS bracket open c plus 2 bracket close equals 7c minus c minus 2 equals 6c minus 2
-(3x-4) = -3x + 4
Trial and error. You know that the answer will be between 2 and 3, closer to 3. 2.8 squared = 7.84 2.82 squared = 7.95 2.828 squared = 7.99 2.8284 squared = 7.999 which is close enough for me.
Roughly close to something near 289.
7(a + 3) = 7*a + 7*3 = 7a + 21
sure... I bet lots of people can simplify this... How 'bout 5x sq -15
x cubed y cubed z squared
3(7a - 5b) + 2(4a - 3b) Multiply the contents of each bracket by the number outside it: 21a - 15b + 8a - 6b Bring like terms together: 21a + 8a - 15b - 6b Combine like terms: 29a - 21b This cannot be simplified further.
(x2y2)3 + (x3y3)2 = 2x6y6.
(x-2)(x+2)= x2+2x-2x-4= x2-4
(:)+< Open bracket, :, close bracket, plus, < less then
you first solve the inside of the bracket and then do the inside answer with the outside numbers.
7C MINUS bracket open c plus 2 bracket close equals 7c minus c minus 2 equals 6c minus 2
2(2*1) = 2(2) = 4
-(3x-4) = -3x + 4
I think I'm answering my own quezstion here but hey. Am I right in saying that (x+0)(x+1) Factorises to x2+ x? I think I am.
