I'm helping you now give me two seconds.
Just multiply the two expressions together.
\(\sf (7x - 3) \times (4x^2 − 3x − 6)\)
No, it's kind of like the last question.
Multiply all the terms in the first parenthesis to all the terms in the second parenthesis.
\(\sf 7x \times 4x^2\) \(\sf 7x \times -3x\) \(\sf 7x \times -6\) \(\sf -3 \times 4x^2\) \(\sf -3 \times -3x\) \(\sf -3 \times -6\)
ok hold on
Yeah, after you find those just combine any like terms and you're done..
Have you got your answers?
In this order 28x^2 -21x -42x -12x^2 9x 18
Your right for all the ones except the first two. The numbers are right but you forgot to combine the exponents so think of x^2 * x as x^2+1 since x has the exponential value of 1. So you would get an exponential value of 3. So it would be 28x^3. And same goes for x * x so it would be x^1+1 which is 2. So it should be -21x^2. 28x^3 -21x^2 -42x -12x^2 9x 18 Now combine like terms (that is terms with same exponent. So what is -21x^2 + (-12x^2)
Yes because 28x^3 is the only term with an exponential value of 3 and -21 + (-12) is like -21 - 12 which is 33. Then you replace the x and exponential value so its -33x^2. Good job, now we can eliminate answe C since the second term is 51x^2 which is wrong. So now what is -42x + 9x?
By the way we can also eliminate B as well since the second term is positive and ours is negative. And yes it is -33x. Last step is to add the 18 to your equation so combine all those answers you just gave me.
Correct so when you look at the answers the only one that matches it is D. I hope this helped you don't forget to close this question and choose the person that was the greatest help to you by hitting best response and have a wonderful day. @Keigh2015
