(2x-10)(x+3)+(x3+1)(x-4) what does it equal to
2 answers:
Answer:
Use the FOIL method.
(2x - 10)(x + 3) = 2x*x + 2x*3 + (-10)*x + (-10)*3
= 2x² + 6x - 10x - 30 {Combine like terms}
= 2x² - 4x - 30
(x³ + 1)(x - 4) = x³*x + x³ *(-4) + 1*x + 1*(-4)
= x⁴ - 4x³ + x - 4
(2x - 10)(x +3) +(x³ +1)(x - 4) = 2x² - 4x - 30 + x⁴ - 4x³ + x - 4
Combine like term
= x⁴ - 4x³ + 2x² - 4x + x -30 - 4
= x⁴ - 4x³ + 2x² - 3x - 34

(2x - 10)(x +3) +(x³ +1)(x - 4) = 2x² - 4x - 30 + x⁴ - 4x³ + x - 4
Combine like term
= x⁴ - 4x³ + 2x² - 4x + x <u>-30 - 4 </u>
= x⁴ - 4x³ + 2x² - 3x - 34
