To multiply (7–√) * (−2–√), we can use the distributive property:
(7–√) * (−2–√) = 7*(-2) + 7*(-√) - (√)*(-2) - (√)*(-√)
Simplifying each term:
7*(-2) = -14
7*(-√) = -7√
(√)*(-2) = -2√
(√)*(-√) = -√ * √ = -√(√) = -√(1) = -√
Summing up the terms:
-14 - 7√ - 2√ - √
Combining like terms:
-14 - 9√
Therefore, the answer is -14 - 9√.
