Answer:
The product of 8x(5x−6) is 40x^2−48x
The product of (x−3)(5x−6) is 5x^2−21x+18
Step-by-step explanation:
<u><em>Verify each option</em></u>
Part 1) The product of 8x(5x−6) is 40x^2−48x
we have
Applying distributive property
Compare with the given value
therefore
The statement is true
Part 2) The product of −4x(2x2+1) is −8x^3−5x
we have
Applying distributive property
Compare with the given value
therefore
The statement is not true
Part 3) The product of (x−3)(5x−6) is 5x^2−21x+18
we have
Applying distributive property
Compare with the given value
therefore
The statement is true
Part 4) The product of (2x+3)(x^2+3x−5) is 2x^3+9x^2+9x−25
we have
Applying distributive property
Compare with the given value
therefore
The statement is not true
