3x+7 = 1. We can describe this equation as a stroy. First x was multiplied by 3 and then 7 was added to it to get 1. Now we need to reverse the story. last thing done was +7, so reversing it gives us -7. 1 -...

(x-5)(x-3)=0 x-5=0 x-3=0 x=5 x=3

To answer this question we observe that y is the product of x^2 and sin(x), so we use the product rule. Then dy/dx = 2x * sin(x) + cos(x) * x^2 The resulting equation can be tidied up by factoring out x and ...

To solve this integral you should use the integration by parts formula, which is uv - integral of vu'. First let x^2 be u, therefore u'(the differential of x^2) = 2x, v' = e^x and therefore v (integral of e^...

Use the moon method. E.g. (x+1)(x+2) multiply x with x multiply x with 2 mutiply 1 with x multiply 1 with 2 If you draw this out it will look like a moon shape. now put the like terms together
