To find the value of the expression ( a^2 - ab - 3b^2 ), you need specific values for ( a ) and ( b ). Without those values, the expression can be simplified or factored, but it cannot be evaluated to a numerical value. If you provide values for ( a ) and ( b ), I can help calculate the result.
ab + 2a + 3b + 6
No
6
6b^2 - 3b / 3b 6b^2 - 1 or ( 6b^2 - 3b) / 3b = 2b - 1 Or (6b^2 - 3b ) / 3b = 3b(2b - ) / 3b = 2b - 1
(a+b)(3b+1)
This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)
ab + 2a + 3b + 6
(2a + b)(a + 3b)
No
6
6b^2 - 3b / 3b 6b^2 - 1 or ( 6b^2 - 3b) / 3b = 2b - 1 Or (6b^2 - 3b ) / 3b = 3b(2b - ) / 3b = 2b - 1
so let's group and then factor ab+2a+3b+6= (ab+2a)+(3b+6)= a(b+2)+3(b+2)= (a+3)(b+2) and that is our final answer! Doctor Chuck
2,3,2a,3a,3b,2b,3b^2,2b^2
(a+b)(3b+1)
Oh, dude, you're hitting me with some math right off the bat! So, like, 3b squared minus 3b is basically 3b times b minus 3b, which equals 3b squared minus 3b. It's like the math version of a magic trick - it looks complicated, but it's just simplifying terms.
If a + b = 6, what is the value of 3a + 3b?
Divide by 6a: 6a(a + 3b)
