If x-1 is a factor of p(x), then p(1)=0 By Factor Theorem ⇒(1)²+(1)+k=0 ⇒1+1+k=0 ⇒2+k=0 ⇒k=−2 (2)Solution: If x-1 is a factor of p(x), then p(1)=0 ⇒2(1)²+k(1)+ √2=0 ⇒2+k+√2=0 ⇒k=−(2+√2) (3)Solution...
find the value of k such that the line y=2x+k is a tangent tu the curve y=6x`2+4x 相关知识点: 试题来源: 解析 题目的意思应该是指,求出k的值,使得y=2x+k,是曲线y=6x2+4x的切线. 直线y=2x+k的斜率为2 对曲线求导可得:y'=12x+4 所以y'=2,得:2=12x+4 x=-1/6 代入曲线可得:...
If m, n, p are non-zero real numbers such that (n+p)=(p+m)=(m+n)=k, find the value of k. ( ) A. -1 or 12 B. -2 C. -1 D. 2 E. 12 or 1 相关知识点: 试题来源: 解析 A (n+p)=(p+m)=(m+n)=(m+n+p)(2(n+m+p)).So (m+n+p)(2(n+m+p))=k...
