-70y^2+90x^3+100yx^2-63xy<br>factor by grouping
Alexeev081 [22]
The idea of grouping is to get the terms in groups that allow you to factor out from each group something that becomes a factor in itself, leaving two factors behind that are alike. Like this: rearrange those terms so they are in this order:
(-70y^2 - 63xy) + (90x^3 + 100yx^2).  Now out of the first set we are going to factor out a -7y, and out of the second set we are going to factor out a 10x^2. When we do this, this is what we get: -7y(10y + 9x) + 10x^2(9x + 10y). As you can see, what's inside both sets of parenthesis is the same, just in a different order. We can factor that out now, leaving (9x + 10y)(10x^2 - 7y). And that is factored by grouping.

<h2><u>Answer:</u></h2><h2>y=x^2 has an inverse but it is not a function</h2><h2><u>Step-by-step explanation:</u></h2><h2>y = x</h2><h2>y=x has an inverse function. y=x is the equation of a line. All line has an inverse function and it is also a function</h2><h2>y = 2x + 1 is the equation of a line.</h2><h2>All line has an inverse function and it is also a function</h2><h2>y = x^2 is the equation of a quadratic Quadratic equation has an inverse but it does not pass vertical line test.Hence it is not a function</h2><h2><u></u></h2><h2><u>Thank you</u></h2><h2><u>sunshinemadison101</u></h2>
